## What Is the Origin?

The origin is where the x-axis and y-axis meet on a graph.

The image below shows what we mean by the origin:

The origin is often denoted by the letter **O**.

### Dictionary Definition

The Oxford English Dictionary defines the origin as "a fixed point from which measurement or motion commences; specifically the point of intersection of the axes in Cartesian coordinates."

## The Cartesian Coordinates of the Origin

The Cartesian co-ordinate of the origin is (0, 0).

This is because the value of the x-axis is 0 and the value of the y-axis is 0.

This means the x-coordinate is 0 and the y-coordinate is 0.

## The Origin on A Number Line

The origin also refers to 0 on a number line.

**Note:** The x-axis and y-axis are number lines. The origin is found at 0 on both axes.
