| | The Cartesian Plane |
 | | The Cartesian plane, named after the mathematician Rene Descartes (1596 - 1650), is a plane with a rectangular coordinate system that associates each point in the plane with a pair of numbers. |
 | | You may also edit the coordinates in the text box, then press enter to show the position of the point. |
 | | The first coordinate of each of the six points will be the year, and we will measure contributions in $10,000 increments, so the first point will be (1,7), the second (3,14.5), etc. |
