Answer: You can put either one of them but they will both be correct.
1. Sample Response: This graph does not represent a proportional relationship because it is not a straight line, and the line does not pass through the origin.
2. It is not a straight line and it automatically means it does not go through the origin which therefore means it is not a proportional relationship.
Explanation: I put the second one but got it right still but be sure to include these ideas:
-The graph is not a straight line.
-The line does not pass through the origin.
-The graph of a proportional relationship must be a straight line that passes through the origin.
