Question

Three vertices of a rectangle are (–2, 1), (–2, –3), and (4, –3)

Answer 1

The answer is C

we know that the x of the unknown vertice is 4, because this is a rectangle and that vertices has to be on the same x line as the point below.
y of the unknown vertice has to be 1 because the vertice to the left needs to be on the same y line as the unknown vertice
