Where is a point located if it has the same x-coordinate as the origin?

If a point has the same x-coordinate as the origin, that means the point could be anywhere on the y-axis.  This means it could be below the x-axis or above, but never on the x-axis.  This means if you drew it on a coordinate plane, the point would always be traveling vertically on the y-axis.

The origin's coordinates are (0, 0), so if a point has the coordinates (0, __), thus having the same x-coordinate as the origin, it will be somewhere along the y-axis.
