Question

Which statement is true about the graphs shown? A) Only graph A represents a proportional relationship. B) Only graph B represents a proportional relationship. C) Graph A and graph B both represent a proportional relationship. D) Graph A and graph B both represent a non-proportional relationship.

Answer 1

The answer A

Explanation:

Only graph A represents a proportional relationship.

Two quantities are proportional to each other if the graph is a straight line through the origin.

Answer 2

I believe the answer is B.

Explanation:

Because a proportional relationship is one where x is proportional (equal) to y, and Graph A does not fall into that category, and Graph B does, the answer should be B.
