Constant of Proportionality Skills

Front

What is the constant of proportionality?

Back

The constant of proportionality is a constant value (k) that relates two proportional quantities in the equation y = kx.

Front

How can the constant of proportionality be found?

Back

The constant of proportionality can be found by calculating the unit rate.

Front

What is the unit rate?

Back

The unit rate is the ratio of two measurements in which the second measurement is one unit, often used to find the cost per item.

If a box of cereal costs $3.59 for 30 oz, what is the unit rate per ounce?

Back

The unit rate per ounce is approximately 12 cents.

Front

What is the equation form of a proportional relationship?

Back

A proportional relationship can be expressed in the form y = kx.

Front

In the equation y = kx, what does 'k' represent?

Back

'k' represents the constant of proportionality.

Front

If the constant of proportionality is 5, what is the relationship between x and y?

Back

The relationship is expressed as y = 5x.

Front

How do you express the constant of proportionality from a table of values?

Back

You express it in the form y = kx, where k is determined by the ratio of y to x.

Front

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

Back

It helps to understand how two quantities are related and allows for predictions based on proportional relationships.
