Question

Name all the points shown that lie on the y-axis.

Short answer

The points that lie on y-axis are$R,O$and$Z$.

Step-by-step solution

Step 1. Observe the figure.

From the figure it can be observed that, it is the$x\text{-}y$ plane with several coordinates$J,K,M,N,O,P,Q,$ and so on are marked on it.

Step 2. Define coordinate of a point.

Coordinate $\left(x,y\right)$ of a point is an ordered pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate.

Step 3. Name the points that lie on y-axis.

They-axis is the axis where value of $x$is zero everywhere.

The y-axis in given graph is shown below:

Here, points $R,O$ and$Z$ are on y-axis.
