For the line segment AB, with A(,), B(,),
its midpoint is E(,)
where
= (+)/2,
= (+)/2
*************************************************
suppose the coordinates of point D is (x, y)
As E(0, 1) is the midpoint of CD, we have

Solving the equations for x and y, we have
x = 3
y = -2
So the coordinates of point D is (3, -2)
