A graph is considered proportional when it meets the criteria that the relationship between the variables represented on the graph is directly proportional. The key characteristic of a proportional relationship is that it forms a straight line that passes through the origin (0,0).

Here's what each option means in the context of determining if a graph is proportional:

1. Straight line: This is a necessary condition for a graph to be proportional. A proportional relationship is graphically represented by a straight line, not a curved one.

2. The line goes through the origin: This is also a crucial condition. For a graph to be p...
