Jaxon reflects the quadrilateral over the y-axis.

Maxine reflects the quadrilateral over the x-axis.

To reflect the quadrilateral across the y-axis, I count how far point A is to the right of the y-axis. Then to find the reflected point, I move point A that far left of the y-axis.

I do the same thing for points B, C, & D.

Then, I plot the points of my reflected figure.
