Constant of Proportionality (COP)

Front

What is the Constant of Proportionality (COP)?

Back

The Constant of Proportionality (COP) is a constant value that relates two proportional quantities. It is the ratio of one quantity to another when they are directly proportional.

How do you find the Constant of Proportionality from a table?

Back

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

Front

What is the formula for the Constant of Proportionality?

Back

The formula for the Constant of Proportionality is k = y/x, where y is the dependent variable and x is the independent variable.

Front

If y = 2x, what is the Constant of Proportionality?

Back

The Constant of Proportionality is k = 2.

Front

What does it mean if the Constant of Proportionality is 1/25?

Back

It means that for every 1 unit increase in the independent variable, the dependent variable increases by 1/25 of that unit.

Front

How can you tell if a graph represents a proportional relationship?

Back

A graph represents a proportional relationship if it is a straight line that passes through the origin (0,0).

Front

What is the significance of the Constant of Proportionality in real-life situations?

Back

The COP helps to understand relationships between quantities, such as speed, density, and price per item, allowing for predictions and calculations.

Front

If the Constant of Proportionality is 40, what does this indicate?

Back

This indicates that for every 1 unit increase in the independent variable, the dependent variable increases by 40 units.

Front

What is the relationship between the Constant of Proportionality and direct variation?

Back

In direct variation, the Constant of Proportionality is the constant ratio between the two variables, indicating that they increase or decrease together.

Front

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

Back

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