Question

Select the correct answer.

Which two points have an undefined slope?
OA (-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

C

Explanation:

(-3,-3),(-3,3)

Answer 2

C

Explanation:

An undefined slope means that the line is vertical and parallel to the y- axis.

A vertical line has equal x- coordinates of the points it passes through.

The only pair where the x- coordinates are equal are

(- 3, - 3) and (- 3, 3) ← undefined slope → C
