Question
### Graph the Line 3y - x = -6

Use the provided graph to plot the line described by the equation 3y - x = -6. Below is an explanation on how we can approach graphing this equation:

1. **Transform the Equation**: 
   Rearrange the equation into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
   
   \[
   3y - x = -6 \\
   \Rightarrow 3y = x - 6 \\
   \Rightarrow y = \frac{1}{3}x - 2
   \]

   Here, the slope (m) is \( \frac{1}{3} \) and the y-intercept (b) is -2.

2. **Plot the Y-Intercept**:
   Start by plotting the y-intercept on the graph. Here, the y-intercept is at (0, -2). Mark this point on the vertical axis.

3. **Use the Slope to Find Another Point**:
   The slope of \( \frac{1}{3} \) means that for every 1 unit we move horizontally to the right, we move up by \( \frac{1}{3} \) units.
   From the point (0, -2), move 3 units to the right and 1 unit up to find another point on the line, which is (3, -1).

4. **Draw the Line**:
   Using a ruler or a straight-edge tool, draw a line through the points (0, -2) and (3, -1) extending it in both directions.

### Graph Description:
The graph displays a standard coordinate plane with x and y axes ranging from -5 to 5. 
- The horizontal axis (x-axis) is labeled from -5 to 5.
- The vertical axis (y-axis) is labeled from -5 to 5.

### Tool Instructions:
At the bottom of the graph interface, there are multiple tool options:
- Line tool: Select to draw straight lines.
- Parabola tool: Select to draw parabola shapes.
- Angle tool: Select to draw angles.
- Circle tool: Select to draw circles.
- Clear All button: Use to clear the graph and start over.

Ensure you use the straight line tool to plot the line \( y = \frac{1
