The problem involves determining the type of quadrilateral formed by the points \( L(-7, -4) \), \( M(-1, -8) \), \( N(1, -5) \), and \( O(-5, -1) \), using the slopes and lengths of the sides.

### Let's break down the information:

1. **Slopes of the sides:**
   - Slope of \( LM = -\frac{2}{3} \)
   - Slope of \( MN = \frac{3}{2} \)
   - Slope of \( NO = -\frac{2}{3} \)
   - Slope of \( OL = \frac{3}{2} \)

2. **Lengths of the sides:**
   - Length of \( LM = 2\sqrt{13} \)
   - Length of \( MN = \sqrt{13} \)
   - Length of \( NO = 2\sqrt{13} \)
   - Length of \( OL = \sqrt{13} \)

### Identifying the quadrilateral:

- The opposite sides \( LM \) and \( NO \) have equal slopes (\(-\frac{2}{3}\)) and equal lengths (\(2\sqrt{13}\)). 
- The opposite sides \( MN \) and \( OL \) also have equal slopes (\(\frac{3}{2}\)) and equal lengths (\(\sqrt{13}\)).

When opposite sides are both equal in length and parallel (having the same slope), the quadrilateral is classified as a **parallelogram**.

Therefore, the quadrilateral \( LMNO \) is a **parallelogram**.

### Tip:
To identify a quadrilateral, always check the slopes and lengths of opposite sides. If both are equal, it's likely a parallelogram!

The points L(-7, -4), M(-1, -8), N(1, -5), and O(-5, -1) form a quadrilateral. Find the desired slopes and lengths, then fill in the words that BEST identifies the type of quadrilateral.
