Question

What is the ordinate of any point on $x-$ axis

Answer 1

The ordinate of a point:

In a coordinate point $(x,y)$ , the $x$ represents abscissa, and the $y$ represents ordinate.

The coordinate of any point on the $x-\mathrm{axis}$ will be $(x,0)$.

Since ordinate is the $y-\mathrm{coordinate}$ of the point which is $0$ here

Hence, the ordinate of any point on the $\mathbf{x}\mathbf{-}\mathbf{axis}$ is $\mathbf{0}$.
