### Explanation

This problem asks you to find the equation of the perpendicular bisector for the line segment determined by the given endpoints. 

Here are the steps you can follow to solve this problem:

1. **Find the Midpoint:** 
    - Use the midpoint formula \((x_{mid}, y_{mid}) = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)\).
    - Substitute the coordinates \((-1, 4)\) and \((-9, -6)\) into the formula.

2. **Calculate the Slope of the Original Line Segment:**
    - Use the slope formula \(m = \frac{y_2 - y_1}{x_2 - x_1}\) where \((x_1, y_1) = (-1, 4)\) and \((x_2, y_2) = (-9, -6)\).

3. **Determine the Slope of the Perpendicular Bisector:**
    - The slope of a line perpendicular to another is the negative reciprocal of the original slope. If the original slope is \(m\), the perpendicular slope will be \(-\frac{1}{m}\).

4. **Formulate the Equation:**
    - Use the point-slope form of a linear equation \( y - y_1 = m(x - x_1) \) with the perpendicular slope and the midpoint coordinates.

By following these steps, you can find the equation of the perpendicular bisector of the given line segment.
