Constant of Proportionality Review

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as 'k' in the equation y = kx.

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

Back

To find the constant of proportionality from a graph, determine the slope of the line, which represents the rate of change between the two quantities.

Front

What does the equation y = kx represent?

Back

The equation y = kx represents a proportional relationship where 'y' is directly proportional to 'x' with 'k' as the constant of proportionality.

If the price of 5 bananas is $1.25, what is the constant of proportionality?

Back

The constant of proportionality is $0.25 per banana.

Front

What is a unit rate?

Back

A unit rate is a comparison of two different quantities when they are combined together, expressed as a quantity per one unit of another quantity.

Front

How can you express a proportional relationship in a table?

Back

In a table, a proportional relationship can be expressed by showing pairs of values that maintain a constant ratio.

Front

What is the relationship between unit price and constant of proportionality?

Back

The unit price is a specific example of the constant of proportionality, representing the cost per single unit of an item.

Front

If y = 3x, what is the constant of proportionality?

Back

The constant of proportionality is 3.

Front

What does it mean if two quantities are proportional?

Back

Two quantities are proportional if they maintain a constant ratio or relationship to each other.

Front

How do you determine if a relationship is proportional from a set of data?

Back

To determine if a relationship is proportional from a set of data, check if the ratios of corresponding values are constant.
