This code will create a plot of the equation z = (-x + y) / A . The value of A  can be changed to change the slope of the plane. For example, if A = 1 , the plane will be a line.

To compile this code, you will need to have the tikz  and pgfplots  LaTeX packages installed. You can then compile the code using the following command:

pdflatex plot.tex

This will create a PDF file called plot.pdf  that contains the plot.
