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

measurement.)
