Let the other endpoint be (a,b)
then (a+3)/2 = 6
a+3 = 12
a = 9
and
(b+5)/2 = 4
b+5 = 8
b = 3
the other endpoint is (9,3)
(your answer would not give you a midpoint of (6,4) , you should have checked it)
find the other endpoint of a line segment with the given midpoint (6,4) endpoint ((3, 5).
6= 3/2 and 4 = 5/2
12=6 and 8 = 10
12-6 and 8 - (-10)
End Point = (6, 18)
