Let’s tackle each question individually.

### Question 5
We need to find the equation of a line that is **parallel** to \( y = -\frac{1}{3}x + 4 \) and passes through the point \( (6, 5) \).

#### Solution:
1. **Identify the slope** of the given line \( y = -\frac{1}{3}x + 4 \), which is \( m = -\frac{1}{3} \).
2. Since parallel lines have the **same slope**, our new line will also have a slope of \( -\frac{1}{3} \).
3. Using the **point-slope form** of a line equation \( y - y_1 = m(x - x_1) \) with point \( (6, 5) \) and slope \( -\frac{1}{3} \):
   \[
   y - 5 = -\frac{1}{3}(x - 6)
   \]
4. Expand and simplify:
   \[
   y - 5 = -\frac{1}{3}x + 2
   \]
   \[
   y = -\frac{1}{3}x + 7
   \]
So, the correct answer for Question 5 is:
\[
\boxed{y = -\frac{1}{3}x + 7}
\]

### Question 6
We are asked about the relationship between the graphs of the lines \( y = -6 \) and \( x = \frac{1}{6} \).

#### Solution:
1. **Analyze each line**:
   - The line \( y = -6 \) is a **horizontal line** with a slope of \( 0 \) (since the slope of a horizontal line is always zero).
   - The line \( x = \frac{1}{6} \) is a **vertical line**, which has an undefined slope (as vertical lines do not have a defined slope).
2. **Perpendicularity**: A horizontal line and a vertical line are always **perpendicular** to each other.

Therefore, the correct answer for Question 6 is:
\[
\text{The lines are perpendicular to each other because the graph of } y = -6 \text{ is a horizontal line with a slope of 0, and the graph of } x = \frac{1}{6} \text{ is a vertical line with a slope that is undefined.}
\]
