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.
