Lesson 11 represent proportional relationships

In the previous lesson students learned that the graph of a proportional relationship lies on a line through the origin. In this lesson, they start to make connections between the graph and the context modeled by the proportional relationship, and between the graph and the equation for the proportional relationship. Given a lesson 11 represent proportional relationships, they think about what situation it might represent and learn the importance of being precise about saying which quantities are represented on each axis MP6.

A — Decide whether two quantities are in a proportional relationship, e. B — Identify the constant of proportionality unit rate in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships. C — Represent proportional relationships by equations. D — Explain what a point x, y on the graph of a proportional relationship means in terms of the situation, with special attention to the points 0, 0 and 1, r where r is the unit rate. The essential concepts students need to demonstrate or understand to achieve the lesson objective. The Problem Set Guidance describes a possible activity to help students make connections between the representations.

To know if a relationship is proportional, you should look at the ratios between the two variables. If the ratio is always the same, the relationship is proportional. If the ratio changes, the relationship is not proportional. Want to join the conversation?
