An endpoint of a segment has coordinates 0,0. The midpoint has coordinates a,b Find the coordinates of the other endpoint.
----
Let the coordinates of the other endpoint be (x,y)
-----
Note: the coordinates of the midpoint are the average of the corresponding
endpoint coordinates.
----
a = (0+x)/2
2a = x
----
b = (0+y)/2
2b = y
-----
Coordinates of the "other" endpoint: (2a,2b)
