Here are the properties that justify each step in the transformation from Line 1 to Line 5:
1. **Line 1 to Line 2: (4x)(6y) = 4 ⋅ (x ⋅ 6) ⋅ y**
- **Property**: Associative Property of Multiplication (specifically grouping the factors)
2. **Line 2 to Line 3: 4 ⋅ (x ⋅ 6) ⋅ y = 4 ⋅ (6 ⋅ x) ⋅ y**
- **Property**: Commutative Property of Multiplication (rearranging the factors)
3. **Line 3 to Line 4: 4 ⋅ (6 ⋅ x) ⋅ y = (4 ⋅ 6)(x ⋅ y)**
- **Property**: Associative Property of Multiplication (grouping the factors together)
4. **Line 4 to Line 5: (4 ⋅ 6)(x ⋅ y) = 24xy**
- **Property**: Simplification and the definition of multiplication (calculating the product)
This step-by-step justification illustrates how different properties of multiplication are applicable throughout the transformation of the expression.
