Have you considered graphing them and finding the fourth corner?

(–2, 1), (–2, –3) -2 appears twice in the x-position 4 appears only once in the x-position. There is a hint, here. (–2, –3), (4, –3). -3 appears twice in the y-position 1 appears only once in the y-position. There is a hint, here.

ok thank you

Well, counting appearances works only when all sides are parallel to coordinate axes. Generally, graph the three points and just LOOK to see where the fourth goes.
