The Cartesian Coordinate System was discovered by Rene Descartes.

The cartesian coordinates are plotted on the cartesian plane

cartesian coordinate isn't a system. the graphs you put on the cartesian coordinate plane can be systems. these graphs can be anything you want them to be. and they are calculate different every time.

the thing to remember about cartesian coordinate planes is the you plot the points of (x,y)

Cartesian coordinate system is used for map making, GPA for cars.
