The constant of variation is 3.6
The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between these two corresponding values. Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity. That means, we can say that if one values will increase then other will automatically decrease and vice versa.
Let say if x and y are two values and k is a constant value, then
According to inverse variation
k = xy or y = k/x
In the given question,
Take the order pair (0.9,4)
As it is an inverse variation, we can substitute it
y=k/x
Now find the constant of variation
4=k/0.9
K=3.6
Therefore, constant of variation is 3.6
