Another name for a coordinate plane is a Cartesian plane. It is named after the mathematician and philosopher René Descartes, who introduced the concept of using two perpendicular number lines to locate points in space. The horizontal line is called the x-axis, and the vertical line is called the y-axis. Points are located on the plane using ordered pairs (x, y).
