Let's analyze and solve the problem step by step:

### Line A:
The equation for Line A is given as:
\[
-6x - 2y = 9
\]
We need to convert this to slope-intercept form (\(y = mx + b\)), where \(m\) is the slope.

1. Isolate the term involving \(y\):
   \[
   -2y = 6x + 9
   \]
2. Divide through by \(-2\) to solve for \(y\):
   \[
   y = -3x - \frac{9}{2}
   \]
Now we can see the slope of Line A is \(m_A = -3\).

### Line B:
The equation for Line B is given as:
\[
y + 1 = -3(x - 9)
\]
We can simplify this by distributing the \(-3\) on the right-hand side.

1. Distribute the \(-3\):
   \[
   y + 1 = -3x + 27
   \]
2. Subtract 1 from both sides:
   \[
   y = -3x + 26
   \]
Now we can see that the slope of Line B is \(m_B = -3\).

### Conclusion:
Since both lines have the same slope (\(m_A = m_B = -3\)), they are parallel.

### Final Answer:
- Slope of Line A: \(-3\)
- Slope of Line B: \(-3\)
- Line A and Line B are **parallel**.

### Tip:
For two lines to be perpendicular, their slopes must be negative reciprocals of each other, meaning \(m_1 \times m_2 = -1\).

Determine whether Line A and Line B are parallel, perpendicular, or neither. Line A: -6x - 2y = 9, Line B: y + 1 = -3(x - 9).
