Constant of proportionality

Front

What is the constant of proportionality?

Back

The constant of proportionality is a constant ratio between two variables that are directly proportional to each other.

Front

If y = kx, what does k represent?

Back

In the equation y = kx, k represents the constant of proportionality.

Front

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

Back

To find the constant of proportionality, divide the value of y by the corresponding value of x for any pair of values.

Front

What is the constant of proportionality if y = 12 when x = 3?

Back

The constant of proportionality is 4, since 12 ÷ 3 = 4.

Front

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

Back

If the constant of proportionality is 2, then y = 2 * 5 = 10.

Front

What does it mean if the constant of proportionality is greater than 1?

Back

If the constant of proportionality is greater than 1, it means that y increases faster than x.

Front

What does it mean if the constant of proportionality is less than 1?

Back

If the constant of proportionality is less than 1, it means that y increases slower than x.

Front

In a proportional relationship, if x doubles, what happens to y?

Back

In a proportional relationship, if x doubles, y also doubles.

Front

What is the constant of proportionality if y = 8 when x = 4?

Back

The constant of proportionality is 2, since 8 ÷ 4 = 2.

Front

If y = 3/10x, what is the constant of proportionality?

Back

The constant of proportionality is 3/10.
