Question

Point A is at (-1, -9) and point M is at (0.5, -2.5).

Point M is the midpoint of point A and point B.
What are the coordinates of point B?

Answer 1

Point B is located at point (2, 4)

Explanation:

Since point M is at the center, you find the distance from point A and add that to the other side.

| -1 - 0.5 | = | -1.5 | = 1.5

| -9 - -2.5 | = | -6.5 | = 6.5

Now we can add that to point M to find point B

0.5 + 1.5 = 2

-2.5 + 6.5 = 4

Point B should be at (2, 4)
