To determine how fast Isabella filled her pool, we need to find the rate at which the water volume is decreasing over time. This rate represents the amount of water filled per minute, which we can calculate as follows:

The rate of change in water volume is constant, so we can use the formula for the rate of change (slope):

\[
\text{Rate} = \frac{\text{Change in water (liters)}}{\text{Change in time (minutes)}}
\]

Using two points from the table, such as:
- Point 1: (2 minutes, 184 liters)
- Point 2: (7 minutes, 94 liters)

The change in water volume is:
\[
184 - 94 = 90 \text{ liters}
\]

The change in time is:
\[
7 - 2 = 5 \text{ minutes}
\]

So, the rate of water flow is:
\[
\text{Rate} = \frac{90 \text{ liters}}{5 \text{ minutes}} = 18 \text{ liters per minute}
\]

This means Isabella filled her pool at a rate of 18 liters per minute.

Here are 5 related questions you might want to consider:
1. What was the initial amount of water in the pool when it started filling?
2. How much time would it take to completely fill the pool?
3. Can you create an equation to model the volume of water over time?
4. What would the volume of water be after 10 minutes?
5. If Isabella changed the rate of filling, how would that affect the total time?

**Tip:** When finding rates, always use points that reflect significant changes for the most accurate results.

Learn how to determine the rate at which Isabella fills her pool by analyzing the rate of change in water volume over time. This problem involves calculating the slope of a line, a key concept in linear functions, and is suitable for students in Grades 6-8.
