I don't really have any ideas. I know what the plane z=-3 looks like... parallel to the xy plane 3 units along the z axis in the negative direction.. but I don't know know what y=z is.

If z= -3 and y= z, then y= -3 seems pretty obvious??? And there is no restriction at all on x is there? In terms of parametric equations, with t as parameter,
