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 slope is the rate at which water fills the pool.

Step-by-step explanation:

Another term for slope is "rate of change."  It describes the change in the dependent variable as the independent variable increases.

We are told the slope is 2; this means that the dependent variable rises 2 for every change in the independent variable.

In the situation of filling a pool with water, the measurements we would have would be the amount of water in the pool to begin with; the amount we end up with in the pool; and the rate at which the water level changes.  The only of these 3 that is a rate is the rate at which the water level changes; this must be the slope.
