### When a point lies on the y-axis what do you know about it's x-coordinate .?

The x-coordinate of any point on the y-axis is 0.
The y-axis is a line perpendicular to the x-axis. Any point on a
line perpendicular to the x-axis has the same x-coordinate. The
y-axis is the line perpendicular to the x-axis through 0, and has
the equation x = 0; similarly, the x-axis is the line perpendicular
to the y-axis through 0 and has the equation y = 0.
