The image shows a number line with two unknown numbers, \( v \) and \( w \), and a question asking if \( v - w \) is positive or negative. Based on the relative positions of \( v \) and \( w \) on the number line, we can determine the sign of \( v - w \).

### Explanation:
1. If \( v \) is to the right of \( w \) on the number line, \( v - w \) will be positive because the value of \( v \) is greater than \( w \).
2. If \( v \) is to the left of \( w \), \( v - w \) will be negative because \( v \) is less than \( w \).

### From the image:
It seems like \( v \) is marked further to the left than \( w \) (near -1), while \( w \) is positioned to the right (near 1). Therefore, \( v \) is smaller than \( w \), meaning \( v - w \) will be **negative**.

Would you like further explanation or have any specific questions?

Here are some related questions to expand your understanding:
1. What happens when \( v \) and \( w \) are equal on the number line?
2. How does subtraction of negative numbers affect the result?
3. Can \( v - w \) be zero if they are placed differently on the number line?
4. How does the distance between two points on a number line relate to their subtraction?
5. What is the significance of the absolute value when comparing numbers on the number line?

**Tip:** When comparing two numbers on a number line, always check their relative positions—numbers further to the right are greater.

The number line shows two unknown numbers, v and w. Is v - w positive or negative?
