Rectangular Coordinate System

Rectangular Coordinate System

by mark laforteza

​Learning Targets

• ​identify the parts and uses of the rectangular coordinate system.

• ​plot a given coordinate on the Cartesian plane.

​Rene Descartes

​The Cartesian Coordinate Plane was introduced by French mathematician and philosopher Rene Descartes (1560-1650).

He used the idea of the Coordinate Plane to translate Geometry problems to Algebra problems, and vice versa.
