IF YOU EXPLAIN HOW YOU GOT YOUR ANSWER I WILL MEDAL AND FAN

OpenStudy (anonymous):

okay graph the points you have first

OpenStudy (anonymous):

then you will see where the missing point is to make a rectangle,

OpenStudy (anonymous):

If you look at the points (11, 7) and (11, -7), you can see they're opposite of each other in a way. |dw:1429202314853:dw| So the last point has to contain 6 and 7. Since it's in the 3rd quad, everything is negative.. so the points have to be (-6, -7)
