Definition of X-Axis. The coordinate plane is formed by the intersection of two number lines, a horizontal number line and a vertical number line. The horizontal number line is called the x-axis.
The x-axis is essentially an infinite number line running horizontally in both positive and negative directions outward from zero. With the use of such a number line, any number can be found and plotted. The y-axis is a similar number line, only running vertically and perpendicular to the first.
