Question

The abscissa of all the points on the $y-axis$ is?

Answer 1

In the coordinate system, the ordinate is the second component of an ordered pair. For example, if $(x,y)$ is an ordered pair, then $y$ is the ordinate here. An ordered pair is used to denote a point in the Cartesian plane and the first coordinate $\left(x\right)$, in the plane, is called the abscissa.

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 the $x-axis$ scaled with the $y-axis$ is called ordinate. The abscissa and ordinate all together are called coordinates.

Abscissa differs as you move on the $x-axis$ from left or right, it is $0$ for all the points on the $y-axis$. In a coordinate system with two axes $x$ and $y$, then the $y$ value is mentioned as $P(x,y)$. The value of $y$ is zero for points located on the $x-axis$.
