To identify whether a graph is proportional or non-proportional, you'll generally look for these characteristics:
- Proportional Graph: Passes through the origin (0,0) and has a constant ratio (straight line that does not change slope).
- Non-Proportional Graph: Does not pass through the origin or has a changing slope (curve or line that starts above or below the origin).
Since I cannot see the specific graphs you are referring to, here’s a general guideline for how you might classify them:
- If the graph is a straight line through the origin, enter '1' (proportional).
- If the graph does not pass through the origin or is not a straight line, enter '2' (non-proportional).
Please analyze the graphs you have and apply this criterion, or provide additional information about the graphs for me to assist you more specifically!
