ordinate {\displaystyle \equiv y}{\displaystyle \equiv y}-axis (vertical) coordinate

Usually these are the horizontal and vertical coordinates of a point in a two-dimensional rectangular Cartesian coordinate system. An ordered pair consists of two terms—the abscissa (horizontal, usually x) and the
