Proportional Relationships in Tables

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 quantity 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

How can you identify a proportional relationship in a table?

Back

A proportional relationship can be identified in a table if the ratios of corresponding values in the two columns are equal.

Front

What does it mean if a table is proportional?

Back

If a table is proportional, it means that as one quantity increases or decreases, the other quantity does so in a consistent ratio.

Front

How do you find the constant of proportionality from a table?

Back

To find the constant of proportionality from a table, divide the value of one quantity by the corresponding value of the other quantity for any pair of values.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship can be expressed in the form y = kx, where k is the constant of proportionality.

Front

If the constant of proportionality is 10, what is the relationship between x and y?

Back

If the constant of proportionality is 10, the relationship can be expressed as y = 10x.

Front

What is an example of a proportional relationship?

Back

An example of a proportional relationship is the relationship between distance and time at a constant speed, such as y = 60x, where y is distance and x is time in hours.

Front

How do you determine if a relationship is not proportional?

Back

A relationship is not proportional if the ratios of corresponding values are not constant or if a table shows inconsistent ratios.

Front

What is the significance of the constant of proportionality in real-world applications?

Back

The constant of proportionality is significant in real-world applications as it helps to model relationships between quantities, such as speed, density, and cost.
