Front

What is the constant of proportionality?

Back

The constant of proportionality is a constant ratio between two quantities that are directly proportional to each other.

Front

Identify the constant of proportionality if y = 5x.

Back

k = 5

Front

What is the constant of proportionality for the table where y = 9x?

Back

k = 9

Front

If the constant of proportionality is 1.50, what does this mean in a real-world context?

Back

It means that for every unit increase in x, y increases by 1.50.

Front

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

Back

Divide the value of y by the value of x for any pair of corresponding values.

Front

If the constant of proportionality is k = 2/3, what does this indicate about the relationship between x and y?

Back

For every 3 units of x, y increases by 2 units.

Front

What is the formula to calculate the constant of proportionality?

Back

k = y/x, where y is the dependent variable and x is the independent variable.

Front

If a table shows values (3, 6), (4, 8), what is the constant of proportionality?

Back

k = 2.

Front

What does it mean if there is no constant of proportionality?

Back

It means the relationship between the variables is not proportional.
