Constant of Proportionality

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities, often expressed as y = kx.

Front

How do you determine if a relationship is proportional?

Back

A relationship is proportional if the ratio of the two quantities is constant.

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 = 3x, what is the constant of proportionality?

Back

The constant of proportionality is 3.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship is typically in the form y = kx, where k is the constant of proportionality.

Front

If the constant of proportionality is 5, what is the value of y when x = 4?

Back

y = 5 * 4 = 20.

Front

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

Back

The constant of proportionality is 2.

Front

If a table shows (0, 0), (1, 2), (2, 4), is it proportional?

Back

Yes, it is proportional with a constant of proportionality of 2.

Front

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

Back

A non-proportional relationship does not have a constant ratio between the two quantities.

Front

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

Back

You can find the constant of proportionality by determining the slope of the line.
