Constant of Proportionality (COP)

Front

What is the constant of proportionality (COP)?

Back

The constant of proportionality (COP) is the constant factor that relates two proportional quantities, often represented as 'k' in the equation y = kx.

Front

Write the equation that represents a constant of proportionality of 18.50.

Back

y = 18.50x

Front

Which equation represents a proportional relationship?

Back

y = kx

Front

If the constant of proportionality is $9 per hour, what is the equation for the relationship between hours (x) and total cost (y)?

Back

y = 9x

Front

What is the constant of proportionality in the equation y = ½x?

Back

1/2

Front

How do you find the constant of proportionality from a table of values?

Back

Divide the output value (y) by the input value (x) for any pair of corresponding values.

Front

What does a graph with a slope of 40 indicate about the constant of proportionality?

Back

The constant of proportionality is 40, meaning for every unit increase in x, y increases by 40.

Front

If y = 22x, what is the constant of proportionality?

Back

22

Front

In the equation y = kx, what does 'k' represent?

Back

'k' represents the constant of proportionality.

Front

If the constant of proportionality is $8 per hour, how much would 5 hours cost?

Back

$40 (calculated as 8 * 5).
