To solve this question, we need to find the additive inverse of the number $-2$. The additive inverse of a number $x$ is the number that, when added to $x$, results in zero. In other words, the additive inverse of $-2$ is $2$, because:

$-2 + 2 = 0$

Looking at the number line in the image:

• Point $R$ is at $-5$,
• Point $P$ is at $-3$,
• Point $S$ is at $-1$,
• Point $Q$ is at $2$.

Since $2$ is the additive inverse of $-2$, the correct answer is D. point Q.

1. What is the additive inverse of $-5$?
2. How is the additive inverse different from the multiplicative inverse?
3. Can a number have the same additive inverse and multiplicative inverse?
4. What is the relationship between the number zero and additive inverses?
5. How would you find the additive inverse of a fraction?

Tip: The additive inverse of any number $x$ is always $-x$, and it helps bring the sum back to zero.
