X-axis

The x-axis is the horizontal number line on a coordinate plane, used to show left and right positions and to name the first number in an ordered pair.

X-intercept

An x-intercept is a point where a graph crosses the x-axis, which means its y-value is 0, and its coordinates have the form (a, 0).
