I'm trying to plot something like x+y=2 in 3D. The image should look like this:(adsbygoogle = window.adsbygoogle || []).push({});

Been trying to do it in Mathematica using Plot3D, but the it treats the input as a function of z.

Another example: Plot3D[x=4,{x,0,10},{y,0,10},AxesLabel{x,y,z}] plots z=4, not x=4.
