:24% of students in a class are girls. if there are less than 30 students in this class, how many students are there? how many girls are there?

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.
