Finally! I've converted the cartesian equations into parametric one and plotted with ParametricPlot3D. ParametricPlot3D[{x = 1 - t, y = t, z = t - 1}, {t, -5, 5}] Thanks a lot for you help! Thanks all!

how? The intersection of that two surfaces is a straight line. There's nothing to find.

Is there any way, in Mathematica, I can plot a straight line in a 3D plot environment? For example: Plot3D[{{y = 1 - x, z = y - 1}}, {x, -5, 5}, {y, -5, 5}] plots two surfaces, not their intersection (which is a straight line). Thank you in advance.
