Cartesian Plane

The cartesian plane is a way of finding out coordinates. In 1609, Rene Descartes was lying in his bed watching a fly on the ceiling, trying to find it's coordinates. In addition to this he develped the Cartesian Plane. This is quite hard to beleive as the Cartesian Plane helps us a lot with mapping. Without it, we would be lost. A cartesian plane consists of a Y axis and a X Axis. One quadrant only consists of positive numbers and a full Cartesian Plane includes positive and negative numbers.
