Question

The coordinate of the midpoint of AR is -3, what is the coordinate of point R?

Answer 1

0

Step-by-step explanation:

A---(-3)---R

-3 is the midpoint of AR. If -3 is the midpoint we need to add 3 to -3 to find point R.

(-3) + 3 = 0

(If we were going to find the coordinate point of A, then we would subtract 3 from -3).
