The equation of x-axis is y = 0.

The horizontal axis is sometimes known as the x-axis. The abscissa and ordinate are two terms that are used to represent a point's position on a graph.

The abscissa is the coordinates of the X-axis on the cartesian plane. It is the distance measured from the Y-axis to the X-axis.

The x-axis points are commonly written as (p, 0), where p is any real number. As a result, the y-coordinate of the x-axis point is 0.

The equation y = 0 is used to represent the x-axis.
