ab·scis·sa

(ăb-sĭs′ə)
The distance of a point from the y-axis on a graph in the Cartesian coordinate system. It is measured parallel to the x-axis. For example, a point having coordinates (2,3) has 2 as its abscissa. Compare ordinate.
ordinate, abscissa - The ordinate or Y axis is vertical; the abscissa or X axis is horizontal.
