y =
OD y = 2x

The answer is

Step-by-step explanation:

The statement

y varies inversely with x is written as

where k is the constant of proportionality

To find k substitute the values of x and y into the equation

From the question

y = 4

x = 6

We have

Cross multiply

k = 4 × 6

k = 24

So the formula for the variation is

Hope this helps you
