Constant of Proportionality

Front

What is the definition of the constant of proportionality?

Back

The constant of proportionality is a constant ratio between two proportional quantities, often represented by 'k'.

Front

How do you identify the constant of proportionality in a proportional relationship?

Back

To identify the constant of proportionality, divide one quantity by the other (y/x) in a proportional relationship.

Front

If y = kx, what does 'k' represent?

Back

'k' represents the constant of proportionality in the equation, indicating how much y changes for a unit change in x.

Front

What does it mean if the constant of proportionality is 'none'?

Back

If the constant of proportionality is 'none', it indicates that the relationship between the two quantities is not proportional.

Front

In the equation y = 2x, what is the constant of proportionality?

Back

The constant of proportionality is k = 2.

Front

If the constant of proportionality is k = 6, what is the relationship between x and y?

Back

The relationship is y = 6x, meaning y increases by 6 units for every 1 unit increase in x.

Front

How can you determine if a set of data points is proportional?

Back

A set of data points is proportional if the ratio of y to x is constant for all points.

Front

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

Back

The constant of proportionality helps to understand and predict relationships between quantities in various real-world scenarios.

Front

Can the constant of proportionality be a negative number?

Back

Yes, the constant of proportionality can be negative, indicating an inverse relationship between the two quantities.

Front

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

Back

An example is the relationship between distance and time at a constant speed, where distance = speed × time.
