Constant of Proportionality

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant factor (k) that relates two proportional quantities, expressed in the form y = kx.

Front

How do you express a proportional relationship?

Back

A proportional relationship can be expressed as y = kx, where k is the constant of proportionality.

Front

If y = 30x, what is the constant of proportionality?

Back

The constant of proportionality is k = 30.

Front

If y = 2x, what is the value of k?

Back

The value of k is 2.

Front

What does it mean if k = 0?

Back

If k = 0, it means that y is always 0 regardless of the value of x, indicating no proportional relationship.

Front

Identify the constant of proportionality in the equation y = 9x.

Back

The constant of proportionality is k = 9.

Front

What is the relationship between x and y in a proportional relationship?

Back

In a proportional relationship, as x increases, y increases at a constant rate determined by k.

Front

If k = 5, what is the equation of the proportional relationship?

Back

The equation is y = 5x.

Front

How can you determine if two quantities are proportional?

Back

Two quantities are proportional if their ratio is constant.

Front

What is the constant of proportionality if y = 1/2x?

Back

The constant of proportionality is k = 1/2.
