Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint.
-midpoint (0, 3), endpoint (-4, 8)
A) (4, 13)
B) (4, -2)
C) (-14, 16)
D) (-12, 18)

To find the other endpoint, use the midpoint formula: ((x1 + x2)/2, (y1 + y2)/2) = (0, 3). Given one endpoint (-4, 8), solve for x2 and y2:  x2 = 2*0 - (-4) = 4  y2 = 2*3 - 8 = -2  Thus, the other endpoint is (4, -2).
