Constant of Proportionality

Front

What is the constant of proportionality in the equation y = kx?

Back

The constant of proportionality is represented by 'k' in the equation y = kx.

Front

How do you determine if a relationship is proportional?

Back

A relationship is proportional if it can be expressed in the form y = kx, where k is a constant.

Front

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

Back

It means that the relationship between the variables is not proportional.

Front

In the equation y = 30x, what is the constant of proportionality?

Back

The constant of proportionality is 30.

Front

If y = 1.50x, what is the value of the constant of proportionality?

Back

Front

What is the constant of proportionality in the equation y = ½x?

Back

The constant of proportionality is 1/2.

Front

Can a proportional relationship have a constant of proportionality equal to zero?

Back

No, a proportional relationship cannot have a constant of proportionality equal to zero, as it would imply no relationship.

Front

What is the graphical representation of a proportional relationship?

Back

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

Front

How can you find the constant of proportionality from a table of values?

Back

You can find the constant of proportionality by dividing the y-value by the corresponding x-value for any pair of values.

Front

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

Back

The constant of proportionality helps to understand the rate of change between two variables in real-world scenarios.
