Question

How do you graph `x = 4` by plotting points?

Answer 1

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.
