Co-ordinates 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 verticle.

Here are some examples:		A - ( 4 , 8 ) B - ( 6 , 2 ) C - ( 2 , -6 ) D - ( -8 , -8 ) E - ( -2 , 2 )

• Drawing a shape by giving the co-ordinates of the vertices.
• Drawing a graph by giving points along the graph.
• Finding patterns between the x and y co-oridnates.
• Used to show the center of transformations.
