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

Identify the constant of proportionality in the equation y = 6x.

Back

k = 6

Front

If y = 15x, what is the constant of proportionality?

Back

k = 15

Front

What does it mean if k = 1/4 in a proportional relationship?

Back

It means that for every 1 unit increase in x, y increases by 1/4 units.

Front

In the equation y = 8x, what is the value of k?

Back

k = 8

Front

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

Back

You can find k by determining the ratio of y to x for any point on the line.

What is the constant of proportionality if y = 40 when x = 1?

Back

k = 40

Front

If the constant of proportionality is 2, what is y when x = 5?

Back

y = 2 * 5 = 10

Front

What is the constant of proportionality in the equation y = 0.06x?

Back

k = 0.06
