Question

A line segment has an endpoint at (3, 2). If the midpoint of the line segment is (6, -2), what are the coordinates of the point at the other end of the line segment?

Answer 1

(9,-6)

Explanation:

The difference between the x coordinates (3 and 6) is 3 and the y coordinates (2 and -2) is -4, so the differences need to be the same from the midpoint to the other point.

6+3=9

-2+(-4)=-6

So the coordinates are (9,-6)
