The midpoint of MN is point P at (–4, 6). If point M is at (8, –2), what are the coordinates of point N?

The midpoint coordinates are the averages of the endpoints, so N = (2P − M). For the x-coordinate, 2(−4) − 8 = −16; for the y-coordinate, 2(6) − (−2) = 14. Therefore, point N is (−16, 14), choice A.
