What is the distance between the points (-30, -10) and (-30, 19) in the xy-plane?

Question

A.
29 units
B.
9 units
C.
20 units
D.
49 units

Answer 1

The two points have the same x-coordinate, so the distance between them is simply the difference in their y-coordinates:

| -10 - 19 | = |-29| = 29

Therefore, the answer is A. 29 units.
