See description below.
Explanation:
Important features of graphs:
- Straight lines are constant rates of change
- Starting high on the left and heading downward to the right is decreasing.
- Flat or horizontal lines mean no change is happening.
The graph describes the water level over time. It begins by decreasing at a steady rate since it is a straight line. It then levels out meaning it stays the same level over a period time. No change happens. It begins decreasing again before leveling out again and not changing over another period of time. It ends by decreasing til the water level is 0 and all water is gone.
