en.wikipedia.org/wiki/Ordinate

In mathematics, ordinate mostly refers to that element of an ordered pair which is plotted on the vertical axis of a two-dimensional Cartesian coordinate system, as opposed to the abscissa. The term can also refer to the vertical axis (typically y- axis) of a two-dimensional graph (because that axis is used to define and ... usually x) and the ordinate (vertical, usually y)—which define the location of ...

en.wikipedia.org/wiki/Abscissa

In mathematics, an abscissa is the number whose absolute value (modulus) is the perpendicular distance of a point from the vertical axis. Usually this is the horizontal coordinate of a point in a two-dimensional rectangular Cartesian coordinate system. The term can also refer to the horizontal axis (typically x-axis) of a ... usually x) and the ordinate (vertical, usually y)—which define the location of ...
