Find the other endpoint of a line segment with the given midpoint and one endpoint.
Endpoint: (0, 0); Midpoint: ( 4, 2)

Ok, here is the y endpoint: 4
what do you think is the x endpoint? 
positive 2?

how zdo you find the endpoint of a segment?

(0,0), (4,2), (x,y).
40 = x4.
X = 8.
20 = y(2).
Y = 4.
