Question
3-9. Graph each line below on the same set of axes.

a. \( f(x) = 3x - 3 \)

b. \( f(x) = -\frac{2}{3}x + 3 \)

### Explanation
For this task, you need to graph the two linear functions on the same coordinate plane. 

- **Function a**: \( f(x) = 3x - 3 \)
  - Slope (m): 3
  - Y-intercept (b): -3

- **Function b**: \( f(x) = -\frac{2}{3}x + 3 \)
  - Slope (m): -\(\frac{2}{3}\)
  - Y-intercept (b): 3

### Graphing Guide
1. **Plot the Y-intercepts**:
   - For (a), start at (0, -3)
   - For (b), start at (0, 3)

2. **Use the Slope for Additional Points**:
   - For (a), from (0, -3), move up 3 units and right 1 unit for the next point.
   - For (b), from (0, 3), move down 2 units and right 3 units for the next point.

3. **Draw the Lines**:
   - Connect the points for each function to see the full line.
   
This visual representation will help you compare the slopes and intercepts of the two functions.
