2000 $750
2010 $1350
A. What is the rate of change and initial value for Elliot’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.
A.) Rate of change = (1350 - 750) / (2010 - 2000) = 600/10 = $60 The initial value is the amount he charged in his first year of business which is $750.
B.) Required equation is given by y - 750 = 60x y = 60x + 750 where x represent the number of years after 2000.
