Equation of a vertical line

The equation of a vertical line is:

`x=`  The same number

Example

`x = 7`

No matter what value y is, x is 7.

`y = 2`              `x = 7`

`y = 1`              `x = 7`

`y = 0`              `x = 7`

`y = -1`        `x = 7`

`y = -2`        `x = 7`

The graph would be plotted as follows.

Plot a vertical line on the graph which goes through the x axis

And would look like this.

Now find the x axis value and y axis value x = 7

This is a vertical line.
