Question
In an inverse variation, x = 6 and y = 
. What is the equation that represents the inverse variation?
- y =
x - y =
- y = -
- y =
x
x x
Hint:
Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
The correct answer is: y =
Here, we are given that in an inverse variation, x = 6 and y = 1/2.
We have to find the relation between x and y.
We have, y = 
=> = k/6
=> k = 3.
Equation: y = .
Hence, the correct option is B.
We can also take the relation as xy = k instead of y = k/x, where k is a constant.
