6 Jake keeps track of the amount of water he uses on his flower garden over the course of the summer. He finds that the less it rains, the more he needs to water the garden to keep his plants healthy and in bloom. This summer the two driest months were June and August, but it rained so heavily in September that he didn’t have to water his garden at all during that month. Which of the following graphs best represents Jake’s water usage this summer? Question 13 TEKS A.2C ABCD
