were 974 students enrolled in the program. Let y be enrollment in the year x, where x = 0
represents the year 2006.
(a) Which of the following linear equations could be used to predict the enrollment y in a given
year x, where x = 0 represents the year 2006? Explain/show work.
A. y = 750x + 56
B. y = 56x + 224
C. y = 224x + 750
D. y = 56x + 750
(b) Use the equation from part (a) to predict the enrollment for the year 2013. Show work.
(c) Fill in the blanks to interpret the slope of the equation: The rate of change of enrollment with
respect to time is ______________________ per ________________. (Include units of
