Find the slope of the line of fit and explain its meaning in the context of the data
80; a student who studies for 0 hours is predicted to earn 80% on the test
O 60, a student who studies for 0 hours is predicted to earn 60% on the test
O10, for each additional hour a student studies, their grade is predicted to increase by 10% on the test
OS; for each additional hour a student studies, their grade is predicted to increase by 5% on the
test
