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 in the equation y = kx?

Back

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

Front

How do you determine if a table represents a proportional relationship?

Back

A table represents a proportional relationship if the ratios of the corresponding values are constant.

Front

Convert 2 meters to centimeters.

Back

2 meters = 200 centimeters.

Front

What is the constant of proportionality in the equation y = 14x?

Back

The constant of proportionality is 14.

Front

If m = 45h, what does this equation represent?

Back

This equation represents a proportional relationship where m (miles) is proportional to h (hours) with a constant of proportionality of 45.

Front

What is the value of k in the proportional relationship if y = 0.5x?

Back

The value of k is 0.5.

Front

How can you identify a non-proportional relationship?

Back

A non-proportional relationship can be identified if the ratios of the corresponding values are not constant.

Front

What is the unit conversion factor from meters to centimeters?

Back

1 meter = 100 centimeters.

Front

If a table shows values (2, 4), (4, 8), and (6, 12), is this a proportional relationship?

Back

Yes, this is a proportional relationship because the ratio of y to x is constant (2).
