Question

Which of the following equations is an example of inverse variation between the variables x and y

Answer 1

so its B

Explanation:

Because y=12/x

Answer 2

The correct answer is option B

Explanation:

The general form of inverse variation between the variables x and y is as following:

`y * x = c` where c is constant

option A : y = x/12 ⇒ x = 12y (wrong option)

option B : y = 12/x ⇒ y * x = 12 (correct option) and c will be equal 12

option C : y = x + 12 ⇒ not similar to the general form (wrong option)

option D : y = 12x (wrong option)

So, the correct option is B
