Question

1. corners of a rectangle: (5,-2), (5,4), (-1,4) and (x,-2). calculate x. 5 0 -1 4

Explanation:

Step1: Identify horizontal sides

Points (5,-2) and (x,-2) share y=-2 (horizontal side). Points (5,4) and (-1,4) share y=4 (horizontal side).

Step2: Match x-coordinates for rectangle

Horizontal sides must be equal, so x-coordinate of (x,-2) equals that of (-1,4). Thus x=-1.

Answer:

-1 (the option with value -1)
