• 12.99
• 5.99
• 9.99
• 7.99

Multiple Choice

What is the capital of France?

• Berlin
• Madrid
• Rome
• Paris

Draw

Add at least three more points to the graph and label them with their coordinates, considering the proportional relationship between the number of months a person has had a streaming movie subscription and the total amount of money they have paid.

Multiple Choice

What is the equation that represents the relationship between $$C$$ , the total cost of the subscription, and $$m$$ , the number of months, given the proportional relationship?

• C = 5.99 * m
• C = 10.99 + m
• C = 7.99 * m
• C = 7.99 - m

Draw

Label the point $$(1, k)$$ on the graph.

Open Ended

Find the value of $$k$$ on the graph and explain its meaning.

Multiple Choice

What situation could be represented by a graph showing a constant increase over time?

• Fluctuating values over time.
• A sudden drop in a variable.
• A constant decrease in a variable.
• Steady growth in a variable over time.

Draw

Label the axes with the quantities in your situation and give the graph a title.

Multiple Choice

What do the coordinates of a point on the graph represent in your situation?

• The coordinates represent the values of the two variables being compared.
• The coordinates indicate the color of the point.
• The coordinates show the time of day.
• The coordinates represent the distance from the origin.
