Question

Write a slope-intercept equation for a line that passes through (-2,1) and (2,-7).

Answer 1

y = -2x -3

Explanation:

slope intercept form: y=mx+b

find slope or m:

m= y2-y1 / x2-x1

after plugging in values.. u get..

m= -2

further plug in one point in the slope intercept form.

you get ...

b= -3

Final plug into equation:

y = -2x -3
