Question

When Lawrence filled his pool, the water line was 4 in. from the edge of the pool. For the next 5 days, Lawrence noticed that the distance between the water line and the edge of the pool increased by 0.5 in./day. What is the slope of the line that models this situation? A. 0.1 B. 0.5 C. 3.5 D. 4

Answer 1

The slope of the line that best models the situation is the rate of change in the level of the pool. From the given problem, the rate of change is 0.5 / day. Thus, the slope is 0.5. The answer to this item is letter B.
