The image shows a number line with the interval shaded from \(-10\) to \(2\), both included (since the points at \(-10\) and \(2\) are solid dots).

In interval notation, this is expressed as:
\[
[-10, 2]
\]
The square brackets indicate that both endpoints are included.

Would you like a more detailed explanation of interval notation, or do you have any further questions?

Here are 5 related questions for practice:
1. How would you express the interval if \(-10\) was not included but \(2\) was included?
2. What is the interval notation for all numbers greater than \(2\)?
3. How do you write the interval from \(-8\) to \(5\) if neither endpoint is included?
4. How would you express the interval from \(0\) to \(\infty\) (infinity)?
5. What is the meaning of open and closed intervals in interval notation?

**Tip:** When using interval notation, always use square brackets \([ ]\) for included endpoints and parentheses \(( )\) for excluded endpoints.
