How do you graph #x=3# on graphing calculator?

A graph of #x=3# would simply be a vertical line through #x=3#. Because there is no y value or y intercept, we assume the slope in undefined, therefore, the line goes strictly vertically through #x=3#.

Just for future reference, if you were to have an equation with #y=#, let’s say #y=4#, the slope would be zero, and the graph would be a straight line horizontally through #y=4# (4 on the y axis).
