To interpret the slope of the line of best fit, which in this case is \( \frac{1}{2} \), we can understand it as the ratio of the change in the number of kills to the change in the number of hitting attempts.
The slope \( \frac{1}{2} \) indicates that for every 2 hitting attempts, Ava makes approximately 1 kill.
Therefore, the accurate statement from the options provided is:
Ava has about 1 kill for every 2 hitting attempts.
