To determine which graph shows the proportional relationship \( y = 2x \), look for the following characteristics:
- Linear Graph: The graph should be a straight line.
- Origin: The line must pass through the origin (0,0) since proportional relationships go through the origin.
- Slope: The slope of the line should be 2, meaning for every 1 unit increase in \( x \), \( y \) increases by 2 units.
If you can provide me with specific descriptions or images of the graphs in question, I can help you identify which one represents the equation \( y = 2x \).
