Constant of Proportionality

Front

What is the constant of proportionality?

Back

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

Front

How can you determine if a table represents a proportional relationship?

Back

A table represents a proportional relationship if the ratio of the values in one column to the values in another column is constant.

Front

What does it mean if a graph is proportional?

Back

A graph is proportional if it passes through the origin (0,0) and has a straight line.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship can be expressed as y = kx, where k is the constant of proportionality.

What is the constant of proportionality in the table: (1,2), (2,4), (3,6)?

Back

The constant of proportionality is 2.

Front

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

Back

You can find it by determining the slope of the line, which is the change in y divided by the change in x.
