The scatter plot shows the number of hours worked, x , and the amount of money spent on entertainment, y , by each of 24 students.
(a) Write an approximate equation of the line of best fit for the data. It doesn't have to be the exact line of best fit.
(b) Using your equation from part (a), predict the money spent on entertainment for a student who works 8 hours.
Note that you can use the graphing tools to help you approximate the line.
