Question

Write an equation in point-slope form of the line that passes through the point (

3,-1)
and has a slope of -2

Answer 1

Look below.

Explanation:

Point slope fromula: y-y1=m(x-x1)

First we have to plug in our points and slope into the formula.

3 will be plugged into x1 while -1 will be plugged into y1.

Since m represents slope we will plug in -2 into m.

Answer: y+1=-2(x-3)
