intercept

This is the term used for the point where a line or curve intersects a specific axis.

The axes are usually labelled with the variables x and y.

It is possible to have x-intercept and y-intercept. Therefore, the name for the point where the line or curve intersects the x-axis is x-intercept, and the name for the point where the line or curve intersects the y-axis is y-intercept.
