Question

The distance between $-9$ and $0$ is:

Answer 1

Determine the distance between $-9$ and$0$.

The absolute value of the difference between two numbers is the distance between them.

$|x–y|$ is the distance between the points $x$ and $y$, which are $–9$ and $0$.

$$\begin{gathered} |x-y|=|-9–0| \\ \Rightarrow =|-9| \\ \Rightarrow =9 \end{gathered}$$

Hence, the distance between $-9$ and $0$ is $\underline{\mathbf{9}}$.
