it says y=16x+181 represents number of students in class where x represents number of hours study required weekly. what is rate of change of number of students in class to number of hours study

since y(x) = 16x + 181
how does y change when x changes by 1?
the slope of the line is 16, meaning that for every increase in x by 1, y decreases by 16.
the slope of the line is the rate of change of y with respect to x.
