a line segment with one end at C (6,5) has a meid point M (4,2) Determine the coordinate of the other endpoint D.

xmid = (x + x)/2
4 = (6 + x)/2
8 = 6 + x
2 = x
ymid = (y + y)/2
2 = (5 + y)/2
4 = 5 + y
- 1 = y
(2, - 1)
4 = (6 + x)/2
8 = 6 + x
2 = x
ymid = (y + y)/2
2 = (5 + y)/2
4 = 5 + y
- 1 = y

(6,5) <-first endpoint
(4,2) <-midpoint
(2,-1) <-second endpoint
We subtracted (2,3) to get from the first to the midpoint, so repeat to get the second endpoint.
