Smallville High School's Principal is concerned about his school’s Advanced Placement (AP) test scores. He wonders if there is a relationship between the students’ performance in class and their AP test scores so he randomly selects a sample of ten students who took AP examinations and compares their final exam scores to their AP test scores. .

AP Score: 5 1 4 2 1 4 2 1 3 5

Final Score %: 97 70 84 66 62 79 73 63 82 90

Create an equation and graph using the points: (5, 97), (1, 70), (4, 84), (2, 66), (1, 62), (4, 79), (2, 73), (1, 63), (3, 82), and (5, 90). Use the equation of your line of best fit to predict the final exam score of another Smallville HS student who scored a 3 on their AP test.​
