You can  put this solution on YOUR website! The midpoint of segment AB is M(3, 4). The coordinates of point A are (-2, 7). Find the coordinates of point B.  
----- 
Let the coordinates of B be (x,y) 
------ 
Then: 
(-2+x)/2 = 3 
--- 
-2+x = 6 
x = 8 
-------------- 
(7+y)/2 = 4 
7+y = 8 
y = 1 
------ 
Ans:: (x,y) = (8,1)
