Question

1. rectangle points: (-4,-1), (2,-1), (2,5) and (-4,y). find y.

4
5
-1
2

Explanation:

Step1: Identify vertical sides

Points (-4,-1) and (-4,y) share x=-4 (vertical line). Points (2,-1) and (2,5) share x=2 (vertical line).

Step2: Match y-coordinates for top side

The top endpoints of vertical sides must have same y. The top of x=2 line is y=5, so top of x=-4 line is y=5.

Answer:

5 (the option with value 5)
