How would one go about making a table of variable values for a multivariable equation? By that I mean, lets say you have the equation x-3y+z=5. It can easily be plotted as a plane but what if I wanted to produce a list of key values so I could make a graph myself? Similar to how the TI's can make a table for single variable equations. I ask because I am tasked with making a pencil and paper graph and it would be nice if I had a table that were say, incremented by x=1. Is there any such way? It gets very tricky with multiple variables.
