Question Analysis
This question involves determining the frequency of a specific value (score 9) in a line plot.

Key Concept Explanation
Frequency in Line Plots: For any value on the number line of a line plot, the frequency is the count of marks (like Xs or dots) placed above that value. It represents how many times the value appears in the dataset.

Step-by-step Solution
Locate the value "9" on the line plot’s number line.
Count the number of marks (or data points) corresponding to 9 in the dataset: the scores are 8,8,9,9,9,10, so 9 appears 3 times.
Conclusion: The frequency of 9 is 3.
