Direct and Inverse Variation Miniflashcard

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 a non-zero constant.

Front

What is Inverse Variation?

Back

Inverse variation is a relationship between two variables where the product of the two variables is a constant. It can be expressed as xy = k, where k is a non-zero constant.

Front

What does 'Neither' variation mean?

Back

'Neither' variation indicates that the relationship between the two variables does not fit the criteria for either direct or inverse variation.

What is the general form of a direct variation equation?

Back

The general form is y = kx, where k is a constant.

Front

What is the general form of an inverse variation equation?

Back

The general form is xy = k, where k is a constant.

Front

If y varies directly with x and y = 10 when x = 2, what is the constant of variation?

Back

k = 5.

Front

If x and y vary inversely and xy = 24, what is y when x = 3?

Back

y = 8.
