This February and March, the middle school students had their most successful food drive, topping last year's total by 57 items. They started the food drive on day 0 with 8 cans of fruit juice which had been donated too late to be included in the November food drive. Contributions poured in at a constant rate of 12 food items per day. By the time the drive was over, the cans covered the cafeteria stage. What is the dependent variable? What is the independent variable? Find the slope described in the situation.

9. This February and March, the middle school students had their most successful food drive,
topping last year's total by 57 items. They started the food drive on day 0 with 8 cans of
fruit juice which had been donated too late to be included in the November food drive.
Contributions poured in at a constant rate of 12 food items per day. By the time the drive
was over, the cans covered the cafeteria stage.
a.
What is the dependent variable?
b. What is the independent variable?
c. Find the slope described in the situation.
d. Find a point described in the situation.
e. Write an equation of the line in point-slope form.
f. Write an equation of the line in slope-intercept form.
g. Use either equation to tell how many food items had been collected by the 10th day.
h. Use either equation to tell how many days it took to collect 488 items
