Proportionality Test Review

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as 'k' in the equation y = kx.

Front

How can you find the constant of proportionality in a proportional relationship?

Back

You can find the constant of proportionality by calculating the unit rate, which is the ratio of the change in the dependent variable to the change in the independent variable.

Front

What characteristics define a proportional graph?

Back

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

Front

What does it mean if a graph does not pass through the origin?

Back

If a graph does not pass through the origin, it indicates that the relationship is not proportional.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity per one unit of another quantity.

Front

How do you determine if a set of data is proportional?

Back

To determine if a set of data is proportional, check if the ratios of corresponding values are constant.

Front

What is the formula for finding the constant of proportionality?

Back

The formula for finding the constant of proportionality is k = y/x, where y is the dependent variable and x is the independent variable.

Front

What does it mean for two quantities to be proportional?

Back

Two quantities are proportional if they maintain a constant ratio or relationship to each other.

Front

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

Back

An example of a proportional relationship is the relationship between distance and time when traveling at a constant speed.

Front

What is the significance of the origin in a proportional graph?

Back

The origin (0,0) represents the starting point of the relationship, indicating that when one quantity is zero, the other quantity is also zero.
