Math grade 10? Really easy but I need help

[From: ] [author: ] [Date: 12-03-07] [Hit: ]
We subtracted (2,3) to get from the first to the midpoint, so repeat to get the second endpoint.-U need grid Papper!......
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)

-
(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.
