8 Students collected data on the earnings of teenagers aged 13 through 18 who work
outside of school, and the number of hours
they work in a week. The line of best of
fit, y = 8.25x + 35.7, where x represents the
number of hours worked, and y represents
the earnings in dollars, was calculated
for the data. One teenager in the study
works 15 hours a week and earns $119.95.
