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, expressed as y = kx.

Front

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

Back

k = 3

Front

In the equation y = kx, what does k represent?

Back

k represents the constant of proportionality between y and x.

Front

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

Back

Identify the slope of the line; the slope represents the constant of proportionality.

Front

What is the constant of proportionality in the equation y = ½x?

Back

k = ½

Front

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

Back

y = 4 * 5 = 20

Front

What does it mean if k = 0 in a proportional relationship?

Back

If k = 0, it means that y is always 0 regardless of the value of x.

Front

Identify the constant of proportionality in the equation y = 2.5x.

Back

k = 2.5

Front

If a table shows values where y = 3x, what is the constant of proportionality?

Back

k = 3

Front

What is the constant of proportionality if y = 10 when x = 2?

Back

k = y/x = 10/2 = 5.
