<P> 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 ( plural axes ) of the system , and the point where they meet is its origin , at ordered pair ( 0 , 0 ) . The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes , expressed as signed distances from the origin . </P>
