Constant of proportionality

Front

What is the constant of proportionality?

Back

The constant of proportionality is a constant value that relates two proportional quantities. It is the ratio of one quantity to another when they are directly proportional.

Front

If y is directly proportional to x, what is the equation that represents this relationship?

Back

y = kx, where k is 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 = 10 when x = 1?

Back

The constant of proportionality is 10.

Front

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

Back

y = 4 * 5 = 20.

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 at a slower rate than x.

Front

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

Back

The constant of proportionality is 4 (12/3 = 4).

Front

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

Back

The constant of proportionality is 2.

Front

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

Back

If x doubles, y also doubles, maintaining the constant of proportionality.

Front

What is the constant of proportionality in the equation y = 45 mph * t?

Back

The constant of proportionality is 45 mph.
