To write the point-slope form of the equation of a line, we can use the formula:
\[
y - y_1 = m(x - x_1)
\]
where \( m \) is the slope and \((x_1, y_1)\) is a point on the line.
Given:
- Slope \( m = 8 \)
- Point \((x_1, y_1) = (-6, 1)\)
Plugging in these values:
\[
y - 1 = 8(x - (-6))
\]
This simplifies to:
\[
y - 1 = 8(x + 6)
\]
So, the point-slope form of the equation of the line is:
\[
y - 1 = 8(x + 6)
\]

### Part 2: Convert to Slope-Intercept Form
To convert to slope-intercept form, we need to isolate \( y \):
Start with:
\[
y - 1 = 8(x + 6)
\]
Distribute the \( 8 \):
\[
y - 1 = 8x + 48
\]
Now, add \( 1 \) to both sides:
\[
y = 8x + 48 + 1
\]
\[
y = 8x + 49
\]
Thus, the slope-intercept form of the equation is:
\[
y = 8x + 49
\]
### Summary
1. **Point-Slope Form:** \( y - 1 = 8(x + 6) \)
2. **Slope-Intercept Form:** \( y = 8x + 49 \)
\[
y - y_1 = m(x - x_1)
\]
where \( m \) is the slope and \((x_1, y_1)\) is a point on the line.
