WORK Which table correctly shows the proportional relationship between the number of hours Kenny works and how much he earns?
How did you decide which table fits the relationship?
What is the constant of proportionality, or unit rate, for this relationship?
What is the "y variable" for this relationship?
What is the "x variable" for this relationship?
Using the form y = k * x, write an equation showing the relationship between the number of hours Kenny works and the amount he earns. (remember - k is the unit rate or constant of proportionality!)
Look at the table showing the proportional relationship between how many messages she can send and the number of minutes. What number should go in the blue square?
What number completes the table?
What is the constant of proportionality, or unit rate, for this relationship?
Emilio wants to create an equation to help predict how many messages Amira can send in a 55-minute class period. Use the form y = k * x to write an equation for Emilio and Fatumo.
What is the unit rate?
What is the constant of proportionality?
What is the constant of proportionality?
Fill in the table
Do the numbers in this table represent a proportional relationship?
WORK The local dam lets 75,200 gallons pass through it over the course of 8 hours on Wednesday. Then on Thursday, the dam lets 141,000 gallons pass through it over the course of 15 hours. Find the constant of proportionality (k) that tells us how many gallons pass through the dam per hour. Find the constant of proportionality.
WORK Alex can run 24 miles in 3 hours. What is his average speed in miles per hour?
WORK The graph below shows the amount of money Janet earned at her new job.
How much does Janet make per hour? In 16 hours? 25 hours? 40 hours?
WORK Mr. Diaz changed his showerhead to conserve water and energy. The graph below shows the relationship between the amount of flow and the duration of the water flow.
Which statement BEST describes the rate of water flow?
WORK The table below shows the cost to attend the school play based on the number of tickets purchased.
How much does one ticket to the school play cost?
WORK Michael’s car can travel 25 miles on one gallon of gas. The cost of gas is $3.75 per gallon. Which equation would calculate the total cost of gas, t, based on the number of miles traveled, n?
Which graph shows a proportional relationship?
