The Algebra 1 class is completing their work on the Graphs and Linear Equations unit. They have been graphing linear equations on a rectangular coordinate plane, also referred to as the Cartesian coordinate plane. The word “Cartesian” is named after the French mathematician and philosopher Rene Descartes (1596-1650). He invented the method of visualizing numbers as points on a graph and equations as geometric figures. Descartes succeeded in merging the fields of algebra and geometry to create Coordinate Geometry.
