Direct Variation Practice

Front

What is direct variation?

Back

Direct variation is a relationship between two variables where one variable is a constant multiple of the other. It can be expressed as y = kx, where k is the constant of variation.

Front

What is the constant of variation (k)?

Back

The constant of variation (k) is the non-zero constant that relates the two variables in a direct variation. It represents the ratio of y to x.

Front

If y varies directly with x and k = 5, what is the equation?

Back

y = 5x

Front

If x = 3 and y = 12 in a direct variation, what is k?

Back

k = 4 (since k = y/x = 12/3)
