Question

PLEASE HELP!

Point A is located at (-2, 2), and D is located at (4, -2). Find the coordinates of the point that lies halfway between A and D.


1) (0, 1)

2) (-1, 1)

3) (1, 0)

4) (1, 1)

Answer 1

3) (1, 0)

Explanation:

The midpoint can be computed as the average of the coordinates.

M = (A + D)/2 = ((-2, 2) +(4, -2))/2 = ((-2+4)/2, (2-2)/2) = (1, 0)

The midpoint is (1, 0).

This is also easily seen on a graph of the points.
