Question

The table shows the height of water in a pool as it is being filled.

The slope of the line through the points is 2. Which statement describes how the slope relates to the height of the water in the pool?

The height of the water increases 2 inches per minute.
The height of the water decreases 2 inches per minute.
The height of the water was 2 inches before any water was added.
The height of the water will be 2 inches when the pool is filled.

Answer 1

The height of the water increases 2 inches per minute

Answer 2

The correct answer is:

The height of the water increases 2 inches per minute.

Step-by-step explanation:

The slope of a line is also called the rate of change. In this case, it is the rate of change of the water. We are told the pool is being filled; this means that the height of the water is increasing. Since the slope, or rate of change, is 2, the water height in the pool raises 2 inches per minute.
