Step-by-step Solution
To graph the line given by the equation \( y = mx + b \) with the values \( m = \frac{2}{3} \) and \( b = 2 \), we can follow these steps:
1. **Identify the y-intercept**: The y-intercept \( b \) is the point where the line crosses the y-axis. For \( b = 2 \), this point is \( (0, 2) \).
2. **Use the slope to find another point**: The slope \( m = \frac{2}{3} \) means that for every 3 units you move to the right (positive x-direction), you move up 2 units (positive y-direction).
Starting from the y-intercept \( (0, 2) \):
- Move 3 units to the right: \( 0 + 3 = 3 \)
- Move 2 units up: \( 2 + 2 = 4 \)
This gives us the point \( (3, 4) \).
3. **Plot the points**: Now we have two points to plot:
- Point 1: \( (0, 2) \)
- Point 2: \( (3, 4) \)
4. **Draw the line**: Connect the two points with a straight line, extending it in both directions.
The graph of the line \( y = \frac{2}{3}x + 2 \) will show a line that rises gently from left to right, crossing the y-axis at \( (0, 2) \) and passing through the point \( (3, 4) \).
If you were to visualize this, it would look like this:
```

The asterisks (*) represent the points \( (0, 2) \) and \( (3, 4) \), and the line would extend infinitely in both directions.
Quick Answer
Plot the points (0, 2) and (3, 4) and draw a line through them.
