Abscissa – Definition and Example

 Definition: 

Abscissa is the value of the X coordinate on a coordinate plane.

In a coordinate plane the abscissa is the X coordinate of a point.

The Horizontal line is called the X axis, and abscissa is the value of the X axis on a coordinate plane.

The distance of a point from the Y axis is called its X coordinate or Abscissa.

The abscissa always comes first in an ordered pair.

In above figure ordered pair of point P is (3,2)

The abscissa of point P (3,2) is 3.

The abscissa of ordered pair (3,2) is 3.
