Question

The abscissa of all the points on the $x$-axis is:

• A. Any number
• B. $0$
• C. $1$
• D. $2$

Answer 1

Answer: (A)

The coordinate of any point in the $x$-axis is $(x,0)$, where $x$ can take any value.

So, abscissa of any point on the $x$-axis is any number.

Hence, we can say that, abscissa of all the points on the $x$-axis is any number because $x$ - axis is a number line which contains infinite real numbers on it.

Therefore, $\left(D\right)$ is correct.
