GCSE Maths> Shape and space> Coordinates
Coordinates are a set of numbers which pin point a specific point on a graph. They are written in the form ( x, y ), where x is the distance along the x-axis, the horizontal, and the y is the distance along the y-axis, the vertical.

Here are some examples:

A - ( 4 , 8 )

B - ( 6 , 2 )

C - ( 2 , -6 )

D - ( -8 , -8 )

E - ( -2 , 2 )

Coordinates have several uses:

Drawing a shape by giving the coordinates of the vertices.
Drawing a graph by giving points along the graph.
Finding patterns between the x and y coordinates.
Used to show the centre of transformations.
