The equation of the line of best fit is given by:

$$ y = 1.1x - 0.2 $$

Here, $$ y $$ represents the weight of the kittens in pounds, and $$ x $$ represents their age in months.

**Interpretation of the Slope (1.1):**

- **Slope ($$1.1$$)**: This value indicates the rate at which the kittens' weight changes with respect to their age. Specifically, it tells us how much the weight ($$ y $$) increases for each additional month of age ($$ x $$).

**Correct Meaning of 1.1:**

- **On average, the kittens that visited the clinic gained **1.1 pounds per month**.

**Why the Other Options Are Incorrect:**

1. **The average age of the kittens was 1.1 months.**
   - *Incorrect*: The slope does not represent the average age; it represents the rate of weight gain with age.

2. **On average, the kittens gained a pound every 1.1 months.**
   - *Incorrect*: This would imply a slope of approximately $$ \frac{1}{1.1} \approx 0.91 $$, not 1.1.

3. **The average weight of the kittens was 1.1 pounds.**
   - *Incorrect*: The slope does not indicate the average weight. The intercept ($$-0.2$$) is related to the weight when age is zero, but it doesn’t represent the average weight.

**Conclusion:**

The slope of **1.1** in the equation signifies that **on average, the kittens gained 1.1 pounds each month**.

**Correct Answer:**

On average, the kittens that visited the clinic gained 1.1 pounds per month.
On average, the kittens gained 1.1 pounds each month.
