Question

Write a slope intercept form for a line that passes through the points (-1,-1) and (2,5).

Answer 1

y=2x+1

Explanation:

First, find the slope by doing the slope formula.

`(y2-y1)/(x2-x1) =(5-(-1))/(2-(-1)) =(5+1)/(2+1) =(6)/(3)=2\\`

Then plug it into y-y1=m(x-x1)

y-5=2(x-2)

y-5=2x-4

y=2x+1

Hope this helps!
