What are Axes in Math?

In mathematics, the term "axes" refers to the reference lines used to create a coordinate system. The coordinate system is used to locate points in a two-dimensional or three-dimensional space. The axes are typically perpendicular lines that intersect at a point called the origin.

The Coordinate Plane

In a two-dimensional coordinate system, the axes form a plane known as the coordinate plane. The horizontal axis is called the x-axis, and the vertical axis is called the y-axis. The x-axis and y-axis divide the coordinate plane into four quadrants: I, II, III, and IV.

Labeling the Axes

The x-axis is labeled with positive values to the right of the origin and negative values to the left of the origin. The y-axis is labeled with positive values above the origin and negative values below the origin.

Using Axes in Graphing

When graphing points on the coordinate plane, the x-coordinate represents the horizontal position of the point relative to the y-axis, and the y-coordinate represents the vertical position of the point relative to the x-axis.
