Explanation:

In a linear - regression context (line of best fit), the slope of the line represents the change in the dependent variable (quiz score) for a one - unit change in the independent variable (hours of study). Here, the independent variable is the time spent on homework per week and the dependent variable is the quiz score. So, the slope represents the change in the expected quiz score for every additional one - hour students spend on their homework.

Answer:

The change in expected quiz score for every additional one hour students spend on their homework.
