You should start by graph each system of equation to find the answer.
In this case when you graph the first system of equations y=-2x-3 and y=2x-1 it would match up with point Z
y=x+4; y=-x+2 would match up with point X
y=-2x-3; y=x+4 would match up with point W
And finally, y=2x-1; y=-x+2 would match up with Y
Hope this was helpful!
