Find 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, often represented in the equation y = kx.

Front

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

Back

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

Front

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

Back

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

Front

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

Back

The constant of proportionality is 3.

Front

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

Back

The equation is y = (1/4)x.

Front

What does it mean if the constant of proportionality is 0?

Back

If the constant of proportionality is 0, it means that y is always 0 regardless of the value of x.

Front

How can you tell if a relationship is proportional?

Back

A relationship is proportional if the ratio of y to x is constant for all pairs of values.

Front

What is the constant of proportionality for the equation y = 5x?

Back

The constant of proportionality is 5.

Front

In the equation y = 2x + 3, is there a constant of proportionality?

Back

No, because the relationship is not proportional due to the +3.

Front

If a table shows (2, 6), (4, 12), (6, 18), what is the constant of proportionality?

Back

The constant of proportionality is 3.
