# Introduction to Co-ordinates

## About this Coordinates activity

So what do you think about the Coordinates? So the pair of numbers in the grid coordinate, but start the activity with sound and learn more about it.

Coordinates are an ordered pair of numbers used to locate points on a plane or a map. A plane is a two-dimensional flat surface that extends infinitely in all directions. In mathematics, the coordinate system used to plot points on a plane is called the Cartesian coordinate system, also known as the rectangular coordinate system.

The Cartesian coordinate system is made up of a horizontal line called the x-axis and a vertical line called the y-axis, which intersect at a point called the origin. Each point on the plane can be identified by its distance from the origin along the x-axis and the y-axis. The x-coordinate is the first number in an ordered pair, and the y-coordinate is the second number. The coordinates are always written in the order (x, y).

Coordinates are used to graph equations and functions and to find the location of a point on a map or a city plan. They are also used in navigation, such as when using a GPS to find your location or to give directions to a destination. Coordinates provide a way to communicate a precise location that can be easily understood and used by others.
