Explanation:

The line of best fit is a predictive model for the relationship between study hours (x-axis) and quiz scores (y-axis). When $x=1$, the corresponding y-value on this line represents the predicted average quiz score for students who report spending 1 hour per week on homework.

It is the predicted average quiz score for a student who spends 1 hour per week on homework.
