Start studying Proportional Relationships. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Given a proportional relationship, students will be able to graph a set of data from the relationship and interpret the unit rate as the slope of the line.

Which graphs represent proportional relationships? Solution: All three graphs pass through the origin (that is, the point (__,__)). Graph C is also a line. So it represents a proportional relationship. Graph A is composed of line segments, but it is not a ray or a line. Graph B is a curve. So neither of these is a proportional relationship.
