By using the given information about the inverse relation, we will get:

  • Equation: y = -28/x
  • Solution: y = -14

How to get the relation between x and y?

First, we know that y varies indirectly with x, then we can write the relation as:

y = k/x.

Where k is a constant.

Then, we know that when y = 7, we have x = -4.

Replacing these we can find the value of k:

7 = k/(-4)

7*(-4) = k = -28

Then the relation between x and y is:

y = -28/x.

Now, we want to find the value of y when x = 2, then we just replace that in the above equation:

y = -28/2 = -14

So we have:

  • Equation: y = -28/x
  • Solution: y = -14
