Constant of Proportionality

Front

What is the constant of proportionality, k, that relates y to x?

Back

The constant of proportionality, k, is the ratio of y to x in a proportional relationship.

Front

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

Back

k represents the constant of proportionality, which indicates how y changes with respect to x.

Front

If y = ½x, what is the value of the constant of proportionality, k?

Back

k = 1/2.

If Maria swims 12 laps in 6 minutes, what is the constant of proportionality, k, in laps per minute?

Back

k = 2 laps per minute.

Front

What does a constant of proportionality of 1/3 indicate about the relationship between y and x?

Back

It indicates that for every 3 units of x, y increases by 1 unit.

Front

How can you determine if two quantities are proportional?

Back

Two quantities are proportional if their ratio is constant.

Front

If the constant of proportionality, k, is 2, what is the relationship between y and x?

Back
