The ordered pair (x, y) is used to denote a point in Cartesian Coordinate system. It is the second of the two terms by which a point is referred to, in a system of fixed Cartesian Coordinate axes. The first coordinate, i.e., x coordinate, is called the abscissa. Cartesian co-ordinate system specifies each point uniquely in a plane by a pair of numerical co-ordinates, which are the distances from the point to two fixed axes, measured in the same unit of length.
The Prime Meridian is the alpha and omega of the lines of longitude, called meridians. They run perpendicular to lines of latitude, and all pass through both poles. Each longitude line is part of a great circle. There is no obvious zero degree point for longitude, as there is for latitude.
