To use the Associative Property to determine which expressions are equivalent, let's analyze the expressions provided. The Associative Property states that the way in which numbers are grouped in multiplication does not change the product.
The original expression is:
\[
-3 \cdot (4x \cdot -2) \cdot -6y
\]
Now, let's break down each response one at a time.
1. **Response 1:**
\[
-3 \cdot (4x \cdot -2) \cdot -6y = 18 - 8x
\]
This is not equivalent since the left side is a multiplication expression, while the right side is a subtraction expression.
2. **Response 2:**
\[
-3 \cdot (4x \cdot -2) \cdot -6y = (-3 \cdot 4x) \cdot (-2 \cdot -6y)
\]
This uses the associative and commutative properties and is therefore equivalent to the left side.
3. **Response 3:**
\[
-3 \cdot (4x \cdot -2) \cdot -6y = -7xy
\]
This response makes a claim about the value being equal to \(-7xy\), which is not guaranteed to be true without evaluating both sides. So it's not demonstrably equivalent.
4. **Response 4:**
\[
-3 \cdot (4x \cdot -2) \cdot -6y = (-3 \cdot 4x) \cdot -2 \cdot -6y
\]
This is correct as it also uses the associative property in a valid manner, making it equivalent.
### Conclusion:
The expressions that are equivalent to the original expression using the Associative Property are **Response 2** and **Response 4**.

Based on the analysis of the expressions provided, both **Response 2** and **Response 4** correctly apply the Associative Property and are equivalent to the original expression \(-3 \cdot (4x \cdot -2) \cdot -6y\).
To summarize:
- **Response 2:** \(-3 \cdot (4x \cdot -2) \cdot -6y = (-3 \cdot 4x) \cdot (-2 \cdot -6y)\) is equivalent.
- **Response 4:** \(-3 \cdot (4x \cdot -2) \cdot -6y = (-3 \cdot 4x) \cdot -2 \cdot -6y\) is also equivalent.
If you need to pick only one response, **Response 2** demonstrates the associative application more explicitly, but both responses are technically correct.
