I think you're incorrect
Apologies for the mistake. Let's use the equation y=x+60 to make the prediction.
If a student spends 5 hours working on their math classwork a week, we substitute x=5 into the equation:
y = 5 + 60
y = 65
Therefore, the best prediction for a student's quiz grade if they spend 5 hours working on their math classwork a week is 65.
