Which input value produces the same output value for the two functions on the graph?

x = −3
x = −2
x = −1
x = 3

x = -2

The line represents the output value (y) for a given input value (x). Where the lines cross, the output values are equal. These lines cross at x=-2.

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
