The midpoint of line segment M N is point P at negative 4 comma 6 If point M is at 8 comma negative 2 , what are the coordinates of point N ?

The midpoint coordinates are the averages of the endpoints: ((8 + x)/2, (-2 + y)/2) = (-4, 6), where (x, y) is point N. Solving gives x = -16 and y = 14, so point N is (-16, 14), choice C.
