Constant of Proportionality

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

Which best describes the relationship represented in this table?

Back

Proportional: A relationship where two quantities maintain a constant ratio.

Front

What is the constant of proportionality when y = 1/4x?

Back

1/4

Front

When we compare quantities, we compare them as _____ over ______.

Back

y over x

Front

The constant of proportionality is the same as finding what?

Back

All of the above (unit rate, unit price).

Front

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

Back

y = 3 * 5 = 15.

Front

What does a proportional relationship look like on a graph?

Back

A straight line that passes through the origin.

Front

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

Back

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

Front

If y = kx and k = 2, what is y when x = 4?

Back

y = 2 * 4 = 8.

Front

What is the unit rate?

Back

The unit rate is the constant of proportionality expressed as a quantity per one unit of another quantity.
