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, defined as k = y/x.

Front

If y = 6x, what is the constant of proportionality?

Back

k = 6

Front

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

Back

k = 5

Front

How do you determine 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 if y = 1.50x?

Back

k = 1.50

Front

If a table shows values (2, 6), (4, 12), (6, 18), is it proportional?

Back

Yes, the constant of proportionality is k = 3.

Front

What is the equation of a proportional relationship?

Back

The equation is in the form y = kx, where k is the constant of proportionality.

Front

Identify the constant of proportionality for y = 8x.

Back

k = 8

Front

If k = 1/5, what is the relationship between y and x?

Back

y = (1/5)x.

Front

What does it mean if k = 0?

Back

If k = 0, it means there is no proportional relationship; y is always 0 regardless of x.
