Question 688143
For Line Segment AB with midpoint of M, determine the coordinates of point B. A(-2,2);  M=(1,1 1/2).  Please show me how to do this.
-----------
The easiest way:
Find the x & y distances from A to M separately (M - A)
For x: 3
For y: -0.5
--------
Add those to point M separately
x: 1 + 3 = 4
y: 1.5 - 0.5 = 1
B is (4,1)
