Suppose 72% of students chose to study Spanish their sophomore year, and that meant that there were 108 such students. How many students chose not to take Spanish during their sophomore year?

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
