Question

What is the point slope form equations could be produced with the points (2 , -1) and (-2,1)

Answer 1

y+1=-1/2(x-2) OR y-1=-1/2(x+2)

Explanation:

1) First lets find the slope:

(1--1)/(-2-2)

2) Solve

2/-4

3) Simplify:

-1/2

4) Now lets put one set of points, and our slope into the point slope formula:

y+1=-1/2(x-2)

5) Now lets put the other set of points and the slope into the form:

y-1=-1/2(x+2)
