the midpoint formula x=%28x1%2Bx2%29%2F2, y=%28y1%2By2%29%2F2
1) E(4,-4), F(1,7)
x=%284%2B1%29%2F2=2.5, y=%28-4%2B7%29%2F2=1.5
Point (2.5, 1.5)
2) G(2,9), H(-3,6)
x=%282%2B%28-3%29%29%2F2=-0.5, y=%289%2B6%29%2F2=7.5
Point (-0.5, 7.5)
3) I(-8,3), J(3,0)
x=%28-8%2B3%29%2F2=-2.5, y=%283%2B0%29%2F2=1.5
Point (-2.5, 1.5)

using the midpoint formula, find the coordinates of the midpoint of the segment whose endpoints are given:
1) E(4,-4), F(1,7)
mid = [(4+1)/2 ; (-4+7)/2] = (5/2,3/2)
------------------------------
2) G(2,9), H(-3,6)
mid = (-1/2,15/2)
------------------------
3) I(-8,3), J(3,0)
mid = (-5/2,3/2)
====================
