Proportional Relationships Representations

Multiple Choice

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?

• y = 2x
• y = 4x
• y = 3x
• y = x/3

Multiple Choice

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

• 120 cups of cooked rice
• 140 cups of cooked rice
• 100 cups of cooked rice
• 80 cups of cooked rice

Multiple Choice

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 $$R$$ ?

• M = R/10
• M = 0.24R
• M = 2.4R
• M = 24R

Draw

Students are selling raffle tickets for a school fundraiser. They collect $24 for every 10 raffle tickets they sell. Label and scale the axes and graph this situation with $$M$$ on the vertical axis and $$R$$ on the horizontal axis. Make sure the scale is large enough to see how much they would raise if they sell 1,000 tickets.

Multiple Choice

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

• Constant at 1.5
• Constant at 3
• Constant at 2
• Not constant

Multiple Choice

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

• y = 2x + 10
• y = 0.5x - 5
• y = 3x + 1
• y = 0.5x + 14

Draw

Graph the proportional relationship between $$x$$ and $$y$$ using the given table data. Use a scale for the axes that shows all the points in the table.

Draw

Draw graphs on the coordinate plane representing the total amount Elena and Jada earned, $$y$$ , after distributing $$x$$ flyers. Use the graph to decide who got paid more after distributing 14 flyers.
