In analytic geometry, a -intercept or vertical intercept is a point where the graph of a function or relation-axis of the coordinate system..

Using equations

-intercept.

If the function is linear and is expressed in slope-intercept form-intercept.

y-intercepts

Some 2-dimensional mathematical relationships such as circles, ellipses, and hyperbolas-intercept. Because functions-intercept.

x-intercepts

Analogously, an x-intercept is a point where the graph of a function or relation-intercepts.

.

In higher dimensions

-intercept of the current–voltage characteristic of, say, a diode. (In electrical engineering is the symbol used for electric current.)
