**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.

## What's in a Name?

Origin means "start" or "beginning". When you count on a number line, you start from 0. When you define a point with Cartesian coordinates, you start from the origin. Imagine you wanted to find the point**(2, 4)**. Starting from the origin:

- go
**2**across (across the x-axis) - go
**4**up (up the y-axis)
