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.

Front

How do we compare quantities in a proportional relationship?

Back

We compare quantities as y over x, where y is the dependent variable and x is the independent variable.

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

What does it mean if a relationship is proportional?

Back

A relationship is proportional if the ratio between the two quantities remains constant.

Front

How can you identify a proportional relationship from a table?

Back

A proportional relationship can be identified if the ratios of corresponding values are equal.

Front

What is an ordered pair in the context of unit rate?

Back

An ordered pair representing the unit rate is (1, k), where k is the constant of proportionality.

Front

What does a graph of a proportional relationship look like?

Back

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

Front

What is the formula for finding the constant of proportionality?

Back

The formula is k = y/x, where k is the constant of proportionality, y is the dependent variable, and x is the independent variable.

Front

If y = 9x, what is the constant of proportionality?

Back

The constant of proportionality is 9.

Front

What is the significance of the slope in a proportional relationship?

Back

The slope of the line in a proportional relationship represents the constant of proportionality.
