For a school field trip, there must be 1 adult to accompany 14 students, 3 adults to accompany 42 students, and 5 adults to accompany 70 students. Show that the relationship between the number of
adults and the number of students is a proportional relationship. Then enter an equation for the
relationship. Let a represent the number of adults and s represent the number of students in your
equation.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

answer: your correct answer is b. d.
