Intercept

Question: What is the practical meaning of the Vertical Intercept in this word problem? The population of California between the years 1990 and 2009 can be described by the function P(t) = 150t + 3661, where *t* is the number of years since 1990 and P(t) is the population, in thousands. So, the slope is 150t and the Vertical Intercept is 3661. What is the practical meaning of the Vertical Intercept in this situation?

Answer: My guess, is that it started at 3661 people in the population? Because If the y-intercept is 3661.. Thats the first dot in teh 0... and the graph...goes up or down from there....

Question: How would you write a Y-intercept slope equation given the slope and one cordinate? How would you write a Y-intercept slope equation given the slope and one cordinate. Please help!

Answer: If your given coordinate is in the form (0,?) then the ? is the y-int. if the coordinate is anything else.....(a,b) then the point slope equation works just solve for y when done... y-y1 = m*(x-x1)

Question: How do you find the slope intercept form? I'm trying to do a math project and part of it is to find the slope intercept form of certain line. This question is: a line with the y-intercept (0,8) and the x intercept (-2,0) I've asked my parents, siblings and even googled it but can't figure out how to solve the problem. Any help?

Answer: Slope intercept form is y=mx + b where b is your y value when x=0 (thus the y intercept). We know that b=8 since at y=8, x=0 (this was given) All we need to know is the slope m. This can be found with the equation (y2-y1)/(x2-x1) No matter what the points look like. Substituting: (8-0)/(0-(-2))=8/2=4. So m =4. The equation is thus y=4x+8

Question: How long does the state take to intercept your taxes for birthing costs? Mine are technically supposed to be here by the 15th but I'm thinking the state will take longer to intercept then that so if anyone has any knowledge about the situation let me know oh and I already contacted local child support they don't know that they only know when it's taken.

Answer: Well i was over paid by unemployment one time when I filed my state income tax return and it took 25 days to receive a letter stating my return was taken by the EDD office.

Question: What's the difference between x-intercept form and y intercept form? I've been told the basic rule for y-intercept is ' y=ax^2+bx+c ' and x-intercept is y=c(x-a)(x-b) but can you elaborate on it? Such as explaining how to spot each one and the differences.

Answer: The x-intercept form is the points that lie on the horizontal line and the y-intercept are the poitns that lie on the vertical line.

Question: Calculating the intercept with a slope and scores showing the difference from line of best fit? How to do you caluclate the intercept when all you have is the slope and also the individual scores with the differences away from the line of best fit. If you could answer i would very much appreciate your input.

Answer: If all you have is the slope, you cannot find the intercept. But if you have a point on the line and the slope, you can. Let's say you have a slope of 2 and a point on the line on (1, 3). You have m, x, and y. You can solve for b: y = mx + b 3 = 2(1) + b 3 = 2 + b 1 = b y = 2x + 1 So you need the slope and a point.

Question: How do you find the Oblique Asymptote intercept and the Horizontal Asymptote intercept in a rational function? My teacher wants us to do this, and she was very unclear about this. I can't even find anything online about the OA intercept. What exactly is it intercepting? The function I graphed? or one of the axis? Clarification on how to find the OA-Int and the HA-Int would be great. This is assuming I already have the HA or OA, so no need to explain how to find those.

Answer: The intercept is where the straight line crosses the y-axis, so if you have the equation of the horizontal asymptote: y=b, you have the intercept "b". It's only slightly more complex for the oblique asymptote: y=mx+b. The intercept is "b".

Question: What is the vertical and horizontal intercept? Consider the graph of the function y = log2(11x + 6) (the log2 is log base 2) What is the vertical intercept? What is the horizontal intercept?

Answer: Like all log functions regardless of the base, it crosses the x axis (ie horizontal intercept) when the argument of the function is equal to 1. Thus: 11x + 6 = 1 ==> x = -5/11. Like all log functions regardless of the base, it is asymptotic to the vertical axis as the argument goes to zero, but it never crosses it. Thus it is asymptotic to the y axis when 11x + 6 = 0 ==> x = -6/11. (Note since it never really crosses the y axis it technically doesn't have a vertical intercept.)

Question: How can I calculate accurately in excell where 2 serioes of data intercept each other? How can I calculate accurately in excell where 2 serioes of data intercept each other i have 2 lines end coordinates for line 1:- (0,0) , (2,6.5) End coordinates for line 2 :- (6.5,6.5) , (8.5,2) How can I work out what point the intercept eachother?

Answer: first find the eaquation of the lines with their corresponding two points. define each line in terms of y ( or x) just be consistent. then equate both lines, you should come up with a value of x ( or y), then you can consequently solve for the other variable.

Question: How to solve a linear equation with only the y intercept and a pair of points? How do I write an equation for a line with the y intercept =4, contains (-6,-1). I really don't understand.

Answer: If the "y-intercept" is 4, that means the line contains the point (0, 4). This equation form is called "point-slope" form: y - a = m(x - b) Where 'a' is a coordinate (0, a) and 'b' is a coordinate in (b, 0) and 'm' is the slope. y - 4 = m(x + 6) m = (-1 - 4) / (-6 - 0) = -5/-6 = 5/6 y - 4 = 5/6 (x + 6)

Question: How is the slope- intercept form derived from the linear equation? How is the slope- intercept form derived from the linear equation?

Answer: a linear equation is a equation in the form of ax + by + c = 0 and slope - intercept form is y = mx + c now converting ax + by + c = 0 to slope - intercept form ax + by + c = 0 => by = - ax - c => y = (-a/b) x + ( -c/a ) which is slope intercept form where slope = -b/c and y-intercept = -c/a

Question: How can i find the y coordinate of the vertical intercept? Find the y-coordinate of the vertical intercept of the line 91 x + 20 y = 30. I know I should set x to 0 but what after that?

Answer: then you get 20y = 30 divide both sides by 20 y=30/20 this simplifies to y=3/2 The y-int = (0,3/2)

Question: How is the y-intercept related to an arithmetic sequence? How is the y-intercept related to an arithmetic sequence?

Answer: In an equation to a line, y = mx + b, the y-intercept (b) is the starting location, or the value for y when x is 0. In an arithmetic sequence, such as u_0 = 1, u_1 = 3, u_2 = 5, etc. u_0 is the place you are starting from. Similarly, your slope, m (rate of change between any two points), corresponds to the common difference, the distance between each successive term in the sequence. The only difference is that arithmetic sequences require integer (whole number) values for the n-s: "u_n = ", whereas the x-values in the "y = " equation can be any real number you can find.

Question: What would some design specifications be for a device that can intercept a bullet? Something that can be carried by a police officer that would detect a bullet being fired at the officer and intercept it. I list some specifications for my engineering class and i dont know where to start. Just some ideas. ALSO if your going to say something rude dont bother answering. Im not stupid i just need some help. I am stressed out and just having some mental blockage, so please just shoot some ideas.

Answer: one way I can think of is what i'm currently developing for exterminating pest birds. the technology to locate the birds can be used to find the direction of the shots are coming from. if the officer is getting shot at (multiple shots that miss) an array of audio devices a can figure out where the sound is coming from and using a powerful computer, some highly illegal infrared and microwave surveillance equipment, a computer looking in that direction with advanced AI video ID software hopefully finding the shooter (with the weapon), sending the results to the officer's pda (or similar device) then as the officer finds cover, a laser (the very high energy type the dod is developing in their R&D labs) is shot to intercept the bullets and break them into harmless pieces. without some serious hacking and theft you can't possibly get your hands on the technology described above.

Question: How do I convert a quadratic function from standard form into intercept form? I need to know how to convert a quadratic function from standard form into intercept form, and the find the zeros of the function, I am really confused on what to do because my teacher didn't explain it too well and my math book doesn't say what to do either. One of my problems is y=x^2+2x-35, so if someone could just show me the steps of what to do so I can finish the rest of my problems, that would be an enormous help. Thank you!

Answer: intercept form: a(x - p)(x - q) SOP is factoring: y = x^2 + 2x - 35 � coefficient of x = a y = (x + 7)(x - 5) ♣♦

Question: How do I change the point slope equation to a slope intercept of a form equation?? This is the point slope equation: y - 2 = 2 ( x + 4), and I need to change it into a slope intercept equation? Can I do this without subtracting or adding numbers from each side? Is there another way? Thank you for everyone who actually answered my question.

Answer: y - 2 = 2(x + 4) y - 2 = 2x + 8 y = 2x + 8 + 2 y = 2x + 10

Question: How to view pics that people send to you on the Samsung Intercept? Just got this new phone. The Samsung Intercept. When someone sends you a txt with a pic attached it has a clickable "download" button next to it. I tried clicking it and it says "downloading". Then does nothing and goes back to saying "download". How can I view the pic?

Answer: That is fascinating. I just got this phone too, and it always shows me the pics in the message thread right next to a text. I just checked the message settings, and the only thing that has to do with "multimedia" messages is a default 20 multimedia (pictures, video, etc) per message thread (conversations with one person). I have never exceeded this limit, so I do not know if goes to "download" after 20. Sounds to me like you have never seen the pics in the message texts. This could also be a network issue. With every cell phone I've ever owned, if I was not in an area that had good service or a high enough service rating 3G (for example), then I could not get photos, videos, etc. until I was in a better service area. I would just get a "download" link on all these other phones. I would test this, and see if it does this everywhere you are or whether it seems to be location specific. Your phone should, by default, be showing the images IN the messaging app next to your texts. Best of luck!

Question: How do I find slope intercept form and point slope form for this algebra problem? Directions: Use the given conditions to write and equation for each line in point slope and slope intercept form Problem: passing through (-2, 2) parallel equation is---> 2x-3y-7=0 I had a bunch of other problems like this that I got right, but the equation was in point slope form, so it was easier. How do I come up with an answer when the equation looks like that? I'm having a big brain fart.

Answer: I can help! First, you want to put the equation in slope intercept form or y= mx + b. So, you want to get y on one side, and move the rest of the terms to the other side with the 0. 3y= -2x + 7 (subtract 2 from both sides and add 7 from both sides of the equation. Because you want y by itself, and 3 is being multiplied by y to make 3y, you want to do the opposite of multiplication and divide both sides of the equation by 3. That will result in y being alone on one side of the equation, giving you the y= portion of y= mx + b. now that we've divided both sides of the equation by 3, we should have: y = -2/3 x + 7/3. It's good to know that parallel lines share the same slope. So we know that the line will have a slope of -2/3. We know that the y- intercept is 2. So, we can form the equation in slope intercept form. y= -2/3 x + 2. ( you can check it by graphing both lines, and they will be parallel. Point slope form is y-y1 = m (x-x1) m represents the slope, and we know it's -2/3. We have a y and x coordinate, so all we have to do is plug in the information. y-2= -2/3(x-(-2)) we know that x - (-2) is x+2, so we change the equation to : y-2= -2/3 (x+2) This is the answer in slope intercept form. For the original equation: y= -2/3x + 7/3, we know that the y intercept is 7/3, so when x is 0, y is 7/3. Therefore, y-7/3= -2/3 (x-0). This is the answer in point slope form for this equation. Sorry for dragging it out step by step, but that's the best way to learn. I hope this helps. Good luck!

Question: How can you put several home screens on the virgin mobile samsung intercept? How do you add up to seven home screens on the samsung intercept?

Answer: i dont recommend having 7 home screens on the samsung intercept, it slows down the phone, but if you want to have 7 download launcher pro on the android market, it only cost a few dollars, once it downlaods go to menu, preferences, homescreen settings and then click number of screens and 7 should be at the bottem

Question: How do you convert slope intercept to general form? Lets say you have the slope and the y-intercept. From just those two, can you find the general form of the line? Doh. Sorry for making myself unclear. I'm not solving this with pencil and paper. I am making a program to convert it for me, and it must work for all possibilities.

Answer: I am guessing that by "general form' you mean AX + BY + c = 0 Y = MX + B becomes -MX + Y - B = 0
