Given the coordinates of one endpoint of line segment AB and its midpoint M, find the coordinates of the other endpoint.
Changes from A to M will be the same as the changes from M to B.
The x coordinate of B will be 2 + 2 = 4 and the y coordinate will be 5 - 4 = 1.
Write that as B(4,1)
The midpoint of
. One endpoint is
