Question

Define abscissa and ordinate.

Answer 1

The distance of a point from the $y-axis$ scaled with the $x-axis$ is called abscissa or $x$ coordinate of the point.

The distance of a point from $x-axis$ scaled with the $y-axis$ is called ordinate or $y$ coordinate of the point.

In the coordinate system, the ordinate is the second component of an ordered pair and the abscissa is the first component.

For example, if $(x,y)$ is an ordered pair, then $y$ is the ordinate here and $x$ is the abscissa. An ordered pair is used to denote a point in the Cartesian plane.

The abscissa and ordinate all together are called coordinates.
