Question

How do you graph `x=0`?

Answer 1

This is the equation of the y-axis. It is a vertical line through the origin.

Explanation:

Any vertical line has the equation `x = square`

This is because it only has an x-intercept and does not intersect they-axis.

Vertical lines cannot be written in standard form because the slope is undefined.

The equation of the line is given by the x-intercept of the line.

In this case `x=0` goes though the origin (x=0), which means this is the equation of the y-axis.

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