To graph the linear equation \( y = -3x + 2 \), we can identify some key points by substituting values for \( x \).

  1. Finding Points:
    • When \( x = 0 \): \[ y = -3(0) + 2 = 2 \quad \Rightarrow \quad (0, 2) \]
    • When \( x = 1 \): \[ y = -3(1) + 2 = -1 \quad \Rightarrow \quad (1, -1) \]
    • When \( x = -1 \): \[ y = -3(-1) + 2 = 5 \quad \Rightarrow \quad (-1, 5) \]
    • When \( x = 2 \): \[ y = -3(2) + 2 = -4 \quad \Rightarrow \quad (2, -4) \]

From these calculations, we have identified the points:

  • \( (0, 2) \)
  • \( (1, -1) \)
  • \( (-1, 5) \)
  • \( (2, -4) \)
  1. Plotting the Points: On a coordinate plane, mark the points \( (0, 2) \), \( (1, -1) \), \( (-1, 5) \), and \( (2, -4) \).

  2. Drawing the Line: Connect these points with a straight line, extending it with arrows on both ends to indicate that it goes on infinitely.

  3. Identifying Characteristics: The slope of the line is -3, indicating it will descend as it moves from left to right. The y-intercept (the point where the line crosses the y-axis) is at \( (0, 2) \).

Based on this analysis, the correct graph representation should show a downward sloping line passing through the points identified, particularly through \( (0, 2) \) and \( (1, -1) \).

Conclusion:

The correct illustration would not match any of the provided options directly. However, the key points to look for are the characteristic downward slope and those specific points derived from your equation. If you have a choice to select graphics, look for one that best matches this description with points like \( (0, 2) \) and has a negative slope.
