To determine which feature of the graph represents how much yarn Vilgot used for the hat, let's analyze the graph.

The problem involves graphing the total weight of yarn used (in grams) on the x-axis and the length of the scarf (in centimeters) on the y-axis. The graph shows that before any length was added to the scarf (when the scarf length was 0 cm), some yarn had already been used for the hat. This is represented by the point where the graph intersects the x-axis.

### Explanation:
The **x-intercept** represents the total amount of yarn used before starting to knit the scarf, which corresponds to the yarn used for the hat. 

Therefore, the correct answer is:
**B) x-intercept**

1. What does the slope of the line represent in this context?
2. How can you determine the amount of yarn used per centimeter of scarf?
3. Why is the y-intercept not relevant for the yarn used in the hat in this case?
4. How can you interpret the relationship between scarf length and yarn used from this graph?
5. If Vilgot used 400 grams of yarn, how long would the scarf be?

**Tip:** The x-intercept often reveals fixed starting values before any increase happens in real-world situations, like the yarn used before the scarf was made.

What feature of the graph represents how much of the yarn Vilgot used for the hat?

This problem focuses on interpreting the x-intercept of a linear graph to determine how much yarn was used for a hat before starting the scarf. It covers key concepts of graph interpretation, linear relationships, and intercepts. Suitable for middle school students in Grades 6-8.
