Just so you know, i googled this so i hope it helps you. 

What you need to do here is figure out how far point U is from the midpoint and use those same numbers in the opposite direction to find V. So... the difference between the two X's is 2 and the difference between the Y's is -16. So if your midpoint is (-5,11) your point Vshould be (7,-27). I did 5+2 because the difference between 3 and 5 is 2, and -11+-16 because the difference between 5 and -11 is -16.
