## abscissa

[ab′sis·ə]
(mathematics)
One of the coordinates of a two-dimensional coordinate system, usually the horizontal coordinate, denoted by x.

## abscissa

abscissa: P, any point; NP, abscissa
In the plane Cartesian coordinate system, the horizontal coordinate of a point on a plane; the x-coordinate, obtained by measuring the distance from the point to the y-axis along a line parallel to the x-axis.

## abscissa

the horizontal or x-coordinate of a point in a two-dimensional system of Cartesian coordinates. It is the distance from the y-axis measured parallel to the x-axis

## abscissa

(mathematics)
The horizontal or x coordinate on an (x, y) graph; the input of a function against which the output is plotted.

The vertical or y coordinate is the "ordinate".

See Cartesian coordinates.
