In 2007 there were 740 students enrolled in an online training program and in 2010 there were 998 students enrolled in the program. Let y be enrollment in the year x where x=0 represents the year 2007.(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 2007? Explain/show work.A. y=258x + 224B. y=258x + 740C. y=86x + 740D. y=86x + 998(b) Use the equation from part (a) to predict the enrollment for the year 2014. 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).
