Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is constant.

Front

What is the constant of proportionality?

Back

The constant of proportionality (k) is the constant value that relates two proportional quantities in the equation y = kx.

Front

Write the equation for a proportional relationship given k=5.

Back

y = 5x

Front

If y = 12x, what is the constant of proportionality?

Back

12

Front

What does the equation y = kx represent?

Back

It represents a linear relationship where y is directly proportional to x.

Front

If the constant of proportionality is 1/4, what is the equation for y when x = 8?

Back

y = 2 (since y = (1/4) * 8)
