The rectangular or Cartesian coordinate system was devised by Rene Descartes. The system consists of a plane containing two mutually perpendicular axes which cross at a point called the origin.
Usually the axes are referred to as the x-axis which is horizontal, and the y-axis which is vertical. Each axis has a negative and a positive direction. Again, conventionally, the positive direction of the x-axis is to the right and that for the y-axis is upwards. These are only conventions since, when studying the motion of objects moving under gravity (among other forces), it is often convenient to use the downward direction as being positive.
The position of any point in the plane is identified by its distances from the origin along the two axes.
Cartesian coordinate system.
A point's y coordinate is its vertical position, or how high or low it is.

The other name for the rectangular coordinate system is the Cartesian coordinate system. You can remember it because cartography is the study of maps, which are generally rectangular.
Rene Descartes developed the rectangular coordinate system.

The rectangular coordinate system is the basis for how we find locations on a map, for example (even though the earth is actually a sphere, this was a basis). I would say it is rather important.
