The term “abscissa” is used in the field of mathematics, particularly in coordinate geometry, to refer to the horizontal or x-coordinate of a point on a two-dimensional plane. In a Cartesian coordinate system, the abscissa represents the distance of a point from the vertical y-axis. It is generally denoted by the letter “x”.

For example, consider the point P(3, 2) on a graph. Here, the abscissa of point P is 3, indicating that it is located 3 units to the right of the y-axis.

The abscissa is an essential component in plotting and analyzing points, lines, and functions on a coordinate plane. It helps determine the specific location of a point in relation to the horizontal axis and allows for accurate measurements and calculations in geometry and algebraic operations.
