From the Fig. 3.8, answer the following : Write the points whose ordinate is 0
Solution:
Given, the figure represents the coordinates of certain points
We have to find the points whose ordinate is zero.
The vertical coordinate of a point in a plane cartesian coordinate system obtained by measuring parallel to the y-axis is called the ordinate of the point.
Ordinate is zero implies the y-coordinate is zero.
From the figure,
The points with y-coordinate zero are
G(5, 0)
I(-2, 0)
O(0, 0)
Therefore, the points whose ordinate is zero are G, I and O.

Summary:
In a two dimensional coordinate system, the x-coordinate is called abscissa and the y-coordinate is called the ordinate. The points whose ordinate is zero are G(5, 0), I(-2, 0) and O(0, 0)
