Coordinates describe the position of a point. They are written as a bracket with a pair of numbers separated with a comma. (4, 6) is an example of coordinates.

The first number is called the x-coordinate. We find it on the horizontal axis.

The second number is called the y-coordinate. We find it on the vertical axis.

Below a point with coordinates (2, 4) is shown. You need to go 2 across and then 4 up to mark the correct point.

A special point on the coordinate grid is the **origin**. This is the point with coordinates (0, 0). The x- and the y-axis cross at the origin.
