I am trying to plot a degenerate parabolic cylinder of the form 0z=(x^2)-y, i.e, y=(x^2). This is a 3DPlot.

How, on earth do I do this???

I am trying to plot this for instance:

Plot3D[{9 - y, y = x^2, 0}, {x, -10, 10}, {y, -10, 10},
MeshStyle -> LightGray, PlotStyle -> Opacity[0.5]]

I know I can't put y=x^2 there... it doesn't cohere. But, how do I input it?
