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, lesson 11 represent proportional relationships, 2gr fe supercharger between the graph and the equation for the proportional relationship. Given a graph, 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.

Lesson 11 represent proportional relationships

One way to represent a proportional relationship is with a graph. We could buy, for example, 4. If the graph represented the cost for different numbers of sandwiches instead of pounds of blueberries , it might not make sense to connect the points with a line, because it is often not possible to buy 4. Even if only points make sense in the situation, though, sometimes we connect them with a line anyway to make the relationship easier to see.

Solve ratio and rate problems using double number lines, tables, and unit rate. Request a Demo See all of the features of Fishtank in action and begin the conversation about adoption. A — Decide whether two quantities are in a proportional relationship, e. 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. Determine the constant of proportionality in tables, and use it to find missing values. Ratios and Proportional Relationships 6. Compare proportional and non-proportional relationships. This can be repeated so that, after 4 students have worked on each situation, all four representations of the proportional relationship are shown.

Lesson 11 Interpreting Graphs of Proportional Relationships. Write an equation for the relationship. Topic C: Connecting Everything Together. Make connections between the four representations of proportional relationships Part 2. Topic B: Non-Proportional Relationships. What courses are you interested in? Interpret proportional relationships represented in graphs. Ratios and Proportional Relationships 7. Describe a situation that could be represented with this graph. C — Represent proportional relationships by equations. This is a good opportunity for students to showcase their collective work and look at the work of others, via posters, a gallery walk, or in small groups. Given a graph, 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 proportional relationship is shown in the graph below.
