Question

Which is an equation for the line that contains the points (-2, 3) and (2, -1)?

Answer 1

Explanation:

First find the slope:

`(-4)/(4) =-1`

This immediately rules out all answers but J.

Answer 2

J

Step 1. Find slope

(-1 - 3)/(2 + 2)

-4/4

m = -1

Step 2. Write equation

y - 3 = -1 (x + 2)

y = -x -2 + 3

y = -x + 1
