Constant of proportionality

Front

What is the constant of proportionality?

Back

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

Front

What does it mean if two quantities are proportional?

Back

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

Front

How do you find the constant of proportionality from a table of values?

Back

Divide the value of y by the corresponding value of x for any pair of values.

Front

If the constant of proportionality is 5, what is y when x = 3?

Back

y = 5 * 3 = 15.

Front

If the constant of proportionality is 1/4, what is y when x = 8?

Back

y = (1/4) * 8 = 2.

Front

What is the formula for finding y in terms of x and the constant of proportionality?

Back

y = kx, where k is the constant of proportionality.
