Constant of Proportionality (Tables)

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 you identify if a table represents a proportional relationship?

Back

A table represents a proportional relationship if the ratio of y to x is constant for all pairs of values.

Front

What does a proportional graph look like?

Back

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

Front

If y = 2x, what is the constant of proportionality?

Back

The constant of proportionality is 2.

Front

If the constant of proportionality is 5, what is the equation of the proportional relationship?

Back

The equation is y = 5x.

Front

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

Back

The constant of proportionality is 2.

Front

In the equation y = 3/4 x, what is the constant of proportionality?

Back

The constant of proportionality is 3/4.

Front

What is the constant of proportionality for the table: (1, 9), (2, 18), (3, 27)?

Back

The constant of proportionality is 9.

Front

If a table shows values (1, 1/2), (2, 1), (3, 3/2), what is the constant of proportionality?

Back

The constant of proportionality is 1/2.

Front

What does it mean if a relationship is non-proportional?

Back

A non-proportional relationship does not have a constant ratio between y and x; the graph does not pass through the origin.
