A set of values that show an exact position.

On graphs it is usually a **pair of numbers**: the first number shows the distance along, and the second number shows the distance up or down.

Example: the point (12,5) is 12 units along, and 5 units up.

There are other types of coordinates:

• map coordinates (North/South, East/West)

• polar coordinates (distance, angle)

• 3-dimensional coordinates

• etc
