A student who did not study for the test is predicted to earn a grade of 59 points. A student who studied for 59 minutes is predicted to earn a grade of 80 points. Each additional minute of study time is associated with an additional 0.8 points on the test. Each additional minute of study time is associated with an additional 59 points on the test. There is a positive linear relationship between the two variables because as the study time increases, then the test grade increases.
