plot the points
we notice that the square is tilted diagnaol
remember that the legnths of the diagonals of a square are equal
therefor the distance between the points (5,1) and (-1,1) is the same as the ohter diagonal (distance is 6)
the other point is probably that disance up or the y vairable
(2,-2)+6 on the y
-2+6=4
(2,4)
answer is (2,4)
