I am trying to find the coordinates of a point in a line. I have one end, and I have the midpoint. What formula should I use to find the one on the end?
The one end is (8,4) and the MIDPOINT is (14, 7). What would I do to find the opposite point?!
thanks!

(8,4) (14,7) (x, y)
x  14 = 14  8
x = 20
y 7 = 7  4
y = 10
(20,10)
