Question

The number of chicken legs depends on how many chickens are in the coop. This is modeled by y=2x and is an example of _____ variation.

Answer 1

this is an example of direct variation

Answer 2

y=2x is an example of direct variation.

Explanation:

Direct variation is mathematical relationship in between two variables which can be expressed by an equation where one variable is equal to a constant multiplied by the other variable.

In the equation y=2x, x and y are the variables and 2 is a constant.

Here it is expressed as an equation where the variable y is equal to the constant 2 multiplied by the other variable x.

Thus we can say that it is an example of direct variation.
