How do you identify the constant of proportionality in verbal descriptions of
proportional relationships?
In this lesson you will learn how to identify the constant of proportionality in verbal descriptions of proportional
relationships by writing an equation of the form
y = mx and solving for m.
Let’s Review
y = dependent variablex = independent variable
m = constant of proportionality y = mxm = y x
In this lesson you have learned how to identify the constant of proportionality in verbal descriptions of proportional
relationships by writing an equation of the form
y = mx and solving for m.
Extension Activities
Research a racing competition of your choice (running, car racing, biking). How long is the race? How much time did it take the top 3
finishers to complete the course? What was each of their constants of proportionality?
Extension Activities
According to legend the King asked Archimedes if his crown was made from pure
gold or if it had some silver in it. Archimedes figured out that the volume of
the crown is 125 cm3 and that the mass was 1.8 kgs. He also knows that 1 kg of gold has a volume of 50 cm3 and 1 kg of silver has a
volume of 100 cm3. Is the crown pure gold? If not, how much silver is in it. Explain your
reasoning and show all of your work.
