Question

Three vertices of a rectangle have coordinates (–3, 1), (7,1), and (7, –4).

Answer 1

The answer is A because a rectangle has sides that go straight down basically -3 there has to be two -3 for x coordinate and two 7 for y coordinate and the missing coordinate also has to line up with the coordinate right next to it so it must have -4 as it's coordinate so basically the coordinate vertically across from it has the same x coordinate and the coordinate horizontal from it has the same y coordinate. So it's (-3,-4)
