Introduction to Coordinate geometry

The things you will learn to do: [br] 1. Determine the distance between two points [br] a. for two points that lie on a horizontal line* [br] b. for two points that lie on a vertical line* [br] c. for two points that lie on an oblique line*[br] [br]*note: The line does not necessarily need to be drawn in.

Coordinate of a point

Choose two random points, A and B, on the graph above. Write the coordinates of these points.
