A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length.

Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, usually at ordered pair.

The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axis, expressed as signed distances from the origin.
