Coordinates

•A grid has an x-axis and a y-axis.

•A point on a grid has two numbers to identify its position. These two numbers are known as the point’s coordinates.

•Coordinates are always written as the number of steps across first, then the number of steps up or down.

Point a) has coordinates of (2,4)

Point b) has coordinates of (4,2)
