Question

The y – axis is the vertical number line.
If the above statement is true then enter 1 and if it’s false then enter 0.

Answer 1

Hint: It has been asked that y – axis a number line and to show that we will first look at the graph and try to analyse whether it represents a number line or not. We will also point out the definition of the number line and see if the y – axis satisfies them or not.

Complete step-by-step answer:
Now we will show that how the graphs looks like:

In this figure we can see that the y – axis contains all the points as we can see on any number line.
The definition of number line is that:
A number line can be defined as a straight line with numbers placed at equal intervals or segments along its length. A number line can be extended infinitely in any direction and is usually represented horizontally.
Now it is clearly mentioned that the number line can be extended infinitely in any direction in the definition so all the properties of the number line matches with the properties of y – axis.
Hence, from this we can conclude that y – axis is a vertical number line.
So, the answer to this question is 1 or true.

Note: We can also solve this question by stating the properties of y – axis and then compare it to the number line. And any line whether it is vertical or horizontal if it satisfies with the definition of number line that it can be represented as one.
