*connection between algebra and geometry through graphs of lines and curves.
−*Enabling geometric problems to be solved algebraically
−*Geometrically visualising algebra
−*introducing to the Cartesian coordinate plane
−*plotting points on the plane
−*reading coordinates for a point from a graph
*A plane is a flat surface which can be extended in any directions.
−*coordinate geometry gives us a way to describe a point on the plane exactly by two numbers.
