Identify Proportional Relationships Practice Test

Marcus claims that the relationship between the side length of a square and its perimeter is proportional. Sophia argues that the relationship between the side length and the area is proportional. To test their claims, they create data for squares with side lengths 2, 4, and 6 units. Which conclusion is correct?

A student analyzes the relationship between hours studied and test scores for five students. The data shows: (2, 76), (3, 82), (4, 88), (5, 94), (6, 100).
