Question

How do you graph the line `x=0`?

Answer 1

It is the equation of the y-axis. It is a vertical line crossing the x-axis at the origin.

Explanation:

All vertical lines have an equation in the form `x = ...`

The number indicates the `x`-intercept.

The line `x = 0` is the equation for the y-axis.

In the same way the equation of the x-axis is `y=0`
