(x + 4, (1/2)y) endpoint
(-3,2) midpoint
Let (a, b) be the other endpoint.....so we have that
(x +4 + a) (1/2)y + b
________ = 3 _________ = -2
2 2
Multiply both sides by 2
x + 4 + a = 6 (1/2)y + b = -4
subtract x + 2 subtract (1/2)y from both sides
from both sides
a = 2 - x b = -4 - (1/2)y
So.....the answer is (2 - x , - 4 - (1/2)y)
