In mathematics, ordinate 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 ordinate is the second of the two terms (often labeled x and y) which define the location of a point in such a coordinate system.

\( (\overbrace{x}^\text{abscissa}, \overbrace{y}^\text{ordinate}) \)


For the point (-7, 3), -7 is called the abscissa and 3, the ordinate.
