Constant of Proportionality Concepts

Front

What is the constant of proportionality?

Back

The constant of proportionality is a constant value (k) that relates two proportional quantities, represented in the equation y = kx.

Front

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

Back

5

Front

What is the form of a proportional relationship equation?

Back

y = kx

Front

In the equation y = 3x, what does the number 3 represent?

Back

The constant of proportionality.

Front

If the constant of proportionality is 8, which equation is correct?

Back

y = 8x

Front

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

Back

The slope of the line represents the constant of proportionality.

Front

If y = 2x, what happens to y when x is doubled?

Back

y also doubles.

Front

What is the relationship between x and y in a proportional relationship?

Back

As x increases, y increases at a constant rate determined by k.

Front

If the constant of proportionality is 1/4, what is the equation?

Back

y = (1/4)x

Front

What does a constant of proportionality of 0 mean?

Back

It means there is no relationship between x and y; y is always 0.
