If the coordinates of A and B are ( x1, y1) and ( x2, y2) respectively, then the midpoint, M, of AB is given by the following formula
(10,-10 )(9,-9)
M =%28x1%2Bx2%29%2F2%28y1%2By2%29%2F2
x= (10+ 9)/2 y=(-10+9)/2
x= 9.5 y= -0.5

If the coordinates of A and B are ( x1, y1) and ( x2, y2) respectively, 
then the midpoint, M, of AB is given by the following formula 														

        (10,-10),  (9,-9)   					

    M = %28x1%2Bx2%29%2F2, %28y1%2By2%29%2F2							

    x = (10+9)/2,  y = (-10+(-9))/2	

    x =   9.5,	   y =	-9.5										

ANSWER.  The midpoint is (9.5,-9.5).

Solved correctly.
