Question

Point A is located at (-4, 9) on the coordinate plane. Point B is located at (-4, - 7)

What is the distance between Point A and Point B?
The distance between Point A and Point B is
units.

Answer 1

d = 17 units

Explanation:

The same x-coordinate (-4) means that AB is parallel to X-axis, so the distance is the difference between the larger y-coordinate and the smaller one:

-7 < 9

d = 9 - (-7) = 9 + 7 = 16
