Data was collected on the amount of time that a random sample of 8 students spent studying for a test and the grades they earned on the test. A scatter plot and line of fit were created for the data.scatter plot titled students' data, with points plotted at 1 comma 75, 2 comma 70, 2 comma 80, 2 comma 90, 3 comma 80, 3 comma 100, 4 comma 95, and 4 comma 100, and a line of fit drawn passing through the points 0 comma 60 and 2 comma 80Find the y-intercept of the line of fit and explain its meaning in the context of the data. 5; for each additional hour a student studies, their grade is predicted to increase by 5% on the test 10; for each additional hour a student studies, their grade is predicted to increase by 10% on the test 60; a student who studies for 0 hours is predicted to earn 60% on the test 80; a student who studies for 0 hours is predicted to earn 80% on the test
