Front

A proportional relationship can be written as an equation in the form ____ = _____  _____

Back

y = kx

Front

Identify the constant of proportionality if k = 5.

Back

k = 5

Front

Determine the constant of proportionality for the table. Express your answer as y = kx if y = 33 when x = 1.

Back

y = 33x

Front

Identify the constant of proportionality if k = 1.50.

Back

k = 1.50

Front

Determine the constant of proportionality for the table. Express your answer as y = kx if y = 2 when x = 1.

Back

y = 2x

Front

What is the definition of the constant of proportionality?

Back

The constant of proportionality (k) is the constant factor that relates two proportional quantities.

Front

If y = kx and k = 4, what is y when x = 3?

Back

y = 12

Front

If the constant of proportionality is k = 1/2, what is the equation of the proportional relationship?

Back

y = (1/2)x

Front

What does it mean if k = 0 in a proportional relationship?

Back

If k = 0, it means there is no proportional relationship; y is always 0 regardless of x.

Front

If y = 10 when x = 2, what is the constant of proportionality?

Back

k = 5
