A teacher surveyed her students to see how long each had studied for the module test. She recorded that information along with the score each student made on his/her test.
The slope or rate of change is 4/9. In the context of this problem, for every 9 minutes spent studying, we predict a student's test score to increase by 4 percentage points.
The y-intercept in this problem is represented by 158/3, which is approximately 53. This means that if a student does not study at all, we predict his or her score to be 53%.
