Lesson 03: Representing Proportional Relationships | Unit 3: Linear Relationships

What is the equation that reflects the relationship between the volume of uncooked rice and the volume of the rice after it is cooked, where $$x$$ represents the volume in cups of uncooked rice and $$y$$ represents the volume in cups of the rice after it is cooked?

Based on the graph, what is the volume of cooked rice for 20 cups of uncooked rice?

Students are selling raffle tickets for a school fundraiser. They collect $24 for every 10 raffle tickets they sell. Suppose $$M$$ is the amount of money the students collect for selling $$R$$ raffle tickets. Which equation reflects the relationship between $$M$$ and $$R$$ ?

What is the constant of proportionality between $$x$$ and $$y$$ in the given table?

What is the equation that represents the proportional relationship between $$x$$ and $$y$$ shown in the table?
