<human>:  How did Cartesian Coordinates come about?
<bot>: Cartesian coordinates were invented by Rene Descartes in the 17th century. They are named after him because he was the first to use them. Cartesian coordinates are a system of coordinates that use two axes, x and y, to represent points in space. The x-axis is the horizontal axis, and the y-axis is the vertical axis. The origin of the coordinate system is at the point (0, 0).
