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 is the constant value (k) that relates two proportional quantities, often represented as y = kx.

Front

If y = 3x, what is the constant of proportionality?

Back

The constant of proportionality is 3.

Front

How do you determine if a relationship is proportional from a table?

Back

A relationship is proportional if the ratios of corresponding values are equal.

Front

What does it mean if a graph is non-proportional?

Back

A non-proportional graph does not have a constant ratio between the x and y values, meaning the relationship is not linear.

Front

If the constant of proportionality is 5, what is the value of y when x = 4?

Back

y = 5 * 4 = 20.

Front

What is the formula for finding the constant of proportionality from a table?

Back

k = y/x, where y is the output and x is the input.

Front

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

Back

k represents the constant of proportionality.

Front

If a table shows values (2, 6), (4, 12), (6, 18), is this proportional?

Back

Yes, because the ratio of y to x is constant (3).

Front

What is an example of a proportional relationship in real life?

Back

An example is the relationship between distance and time at a constant speed.
