**Write the equation of the line fully simplified slope-intercept form.**

In the graph presented, there is a Cartesian plane with both x and y-axes labeled. The x-axis ranges from -12 to 12, and the y-axis also ranges from -12 to 12. There is a straight line passing through the plane.

The line appears to intersect the y-axis at approximately -8 and slopes upwards towards the right. To write the equation of the line in slope-intercept form, use the formula:

\[ y = mx + b \]

Where \( m \) is the slope and \( b \) is the y-intercept.

### Steps to Determine the Equation:

1. **Identify Two Points on the Line:**
   - The line intersects the y-axis at (0, -8).
   - It passes another grid point, for example at (4, -6)

2. **Calculate the Slope (m):**
   - Use the slope formula: 
     \[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
   - Using the points (0, -8) and (4, -6):
     \[ m = \frac{-6 - (-8)}{4 - 0} = \frac{2}{4} = \frac{1}{2} \]

3. **Write the Equation:**
   - With the slope \( m = \frac{1}{2} \) and y-intercept \( b = -8 \), the equation is:
     \[ y = \frac{1}{2}x - 8 \]

This is the fully simplified slope-intercept form of the line shown in the graph.
