Question

Which two points have a undefined slope

A.(-1, 1) and (1, -1)

B.(-2, 2) and (2,2)

C.(-3, -3) and (-3,3)

D.(-4,-4) and (4, 4)

Answer 1

Answer: C

Explanation:

Answer 2

C.(-3, -3) and (-3,3)

Explanation:

When we have a vertical line the slope is undefined.

That means the x values stay the same

C.(-3, -3) and (-3,3)

This has the same x values

m = (y2-y1)/(x2-x1)

=( 3- -3)/(-3 - -3)

(3+3)/(-3+3)

6/0
