Solve the problem.The graph shows the hours studied and the exam grades obtained on a finite math exam for 8 students. (The two points on the line do not represent any of the eight students.) The line of best fit, the line graphed on the coordinate system, can be used to approximate the test grade the average student receives for the number of hours they study. 
Find the equation of the line of best fit. Then use the equation to estimate a test grade for a student who has studied for 6 hour(s).
