Question

How do you graph `x=7`?

Answer 1

A vertical line where `x=7`

Explanation:

The line `x=7` is a vertical line which crosses the `x`-axis at `7`

Vertical lines cannot be written in the usual way of `y = mx+c` because the slope is infinite and the `y`- values have no effect on the line at all.

Any value of `y` will have the same `x`-value of `7`
