Explanation:
Logic: The equation y = 0 represents a horizontal line where the y-coordinate is always zero. This line is the x-axis itself. We need to identify which of the given graphs shows this.
Analysis of Graphs:
- Graph 1: This graph shows a horizontal line along the x-axis. For every value of x, y is 0.
- Graph 2: This graph shows a horizontal line at y = 1. For every value of x, y is 1, not 0.
- Graph 3: This graph shows a diagonal line passing through the origin with a positive slope. The y-value changes as x changes.
Conclusion:
Graph 1 correctly represents the function y = 0.
Answer: Graph 1
