Proportiona vs Non- Proportional

Front

What is the definition of 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

How can you identify a proportional relationship on a graph?

Back

A proportional relationship on a graph is identified by a straight line that passes through the origin (0,0).

Front

What is a non-proportional relationship?

Back

A non-proportional relationship is a relationship where the ratio between two quantities is not constant.

Front

What does the unit rate represent in a proportional relationship?

Back

The unit rate represents the amount of one quantity for every one unit of another quantity.

Front

How do you calculate the unit rate from a proportional relationship?

Back

To calculate the unit rate, divide the value of one quantity by the value of the other quantity when the second quantity is equal to 1.

Front

What is the significance of the slope in a proportional relationship?

Back

The slope of a line in a proportional relationship represents the constant ratio between the two quantities.

Front

Can a graph that does not pass through the origin be proportional?

Back

No, if a graph does not pass through the origin, it cannot represent a proportional relationship.

Front

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

Back

An example of a proportional relationship is the speed of a car, where distance traveled is proportional to time taken at a constant speed.

Front

What is the formula for finding the unit rate?

Back

The formula for finding the unit rate is: Unit Rate = Total Quantity / Number of Units.

Front

How can tables be used to determine if a relationship is proportional?

Back

Tables can be used to determine if a relationship is proportional by checking if the ratios of corresponding values are constant.
