Solved Examples on Y-Axis

Ques: Which of the following graphs has a point P on the y-axis?

Choices:

A. Graph 1
B. Graph 2

Correct Answer: A

Solution:

Step 1: The coordinate plane is formed by the intersection of two number lines, a horizontal number line and a vertical number line. The vertical number line is called the y-axis
Step 2: Graph 1 has the point P on the vertical number line i.e., on the y-axis.

Ques: Which of the following points lie on y-axis?

Choices:

A. $1, 0$
B. $-1, -1$
C. $0, 1$
D. $1, 1$

Correct Answer: C

Solution:

Step 1: We know that, the ordinate of a point on the y-axis is equal to zero
Step 2: So, point $0,1$ lies on y-axis.
