### Geometry Problems

1. **Midpoint and Length Calculation of Line Segment AB**
   - The endpoints of \( AB \) are \( A(-4, -8) \) and \( B(-1, 4) \).
   - **Task:**
     - Find the coordinates of the midpoint \( M \).
     - Determine the length of \( AB \).

2. **Determining Endpoint Using Midpoint**
   - The midpoint of \( EF \) is \( M(1, -1) \).
   - One endpoint is \( E(-3, 2) \).
   - **Task:**
     - Find the coordinates of endpoint \( F \).

### True or False Statement Evaluation

3. **Collinearity Check**
   - **Statement:**
     - Points \( A \), \( B \), and \( R \) are collinear.
   - **Task:**
     - Use the provided diagram to decide if the statement is true or false.

### Notes:

- **Graph/Diagram Details:**
  - There is a reference to a diagram associated with checking collinearity, but the diagram itself is not visible or described.
  
- **Additional Information:**
  - It appears that some handwritten calculations are noted, indicating operations related to \( AB = 11 \) and equations involving \( x \) values.
