Without using distance formula, show that points `(-2, -1), `(4, 0)`, `(3, 3)`, and `(-3, 2)` are the vertices of a parallelogram.

Explanation

To show that the points \((-2, -1)\), \((4, 0)\), \((3, 3)\), and \((-3, 2)\) are the vertices of a parallelogram without using the distance formula, we can use the concept of slopes. If both pairs of opposite sides have the same slope, then the sides are parallel, which is a property of parallelograms.

### Step-by-Step Solution:

1. **Identify the Points**:
Let the points be:
- \( A(-2, -1) \)
- \( B(4, 0) \)
