Plotting Points

We describe the position of a point by using co-ordinates, a pair of values.

The co - ordinates of the four points on the graph are:

  • Point A (2,1)
  • Point B (4,-1)
  • Point C (-2,-3)
  • Point D (-2,2)

This picture shows a set of graph axes and plots four sets of co-ordinates (2,1), (4,-1), (-2,-3), (-2,2)
