How do you graph x = 4 by plotting points?

Put a point at any repetitive 'y' value along the 'x' values of 4.

Explanation:

ALL graphing is about plotting calculated points on a defined grid and connecting them for a continuous image of the expression.

It works even when the "solution" is a straight line on a fixed variable. Set up a table of 'x' and 'y' values and then plot them on a coordinate plane (graph). In this case, the 'x' never changes from the value 4, so the table might look like this:
x" " y
4" "-3
4" "-2
4" "-1
4" "0
4" "1
4" "2
4" "3

You will end up with a straight line perpindicular to the x-axis at the x = 4 value across all values of y.
