## alli404 2 years ago Write an Equation in slope intercept, point slope, or standard form for the line with the given information. Explain why you chose the form you used. A. passes through (-1,4) and (-5,2) B. Slope 2 intercept -4 C. has an x intercept of 6 and a y intercept of 3 D. Passes through (1,2) with slope -5/3

1. zordoloom

Do you know how to find the slope between 2 points?

2. alli404

3. zordoloom

Subtract the y values and x values, then divide the remaining y/x

4. zordoloom

So for A. (-1,4) and (-5,2) (2-4) and -5-(-1) so -2/-4=....1/2 so the slope for the points (-1,4) and (-5,2) is 1/2

5. zordoloom

Now pick any of the points, either (-1,4) or (-5,2) and using the slope that you just found, write an equation for the line. You will use the point slope formula.

6. zordoloom

So I'll pick the point (-1,4) and with the slope 1/2 write the following formula y-4=(1/2)(x-(-1).....y=4=.5(x+1)....This will be the answer for A
