Answer:
Explanation:
Image your graph where the x-axis represents time (hours), and the y-axis repesents number of magazines to deliver.
Derek starts (at zero time) with 80 magazines to deliver. Notice that after 2 hours, he has 60 left to deliver. Therefore, he is delivering 10 magazines per hour. And after 8 hours, he will have delivered all the 80 magazines.
The answer is #3, he delivers 10 magazines per hour.
Slope is -10/1 because technically, starting with 80, he goes down by 10 each hour resulting in a negative slope.
