Question

Find the constant of variation k for the inverse variation. Then write an equation for the inverse variation.
y = 5 when x = 7.5

Answer 1

General form of inverse variation:

\(y = \dfrac{k}{x}\)

Now plug in your values of x and y and solve for k.
That is the constant of variation.
Then rewrite the general form again with the value you found for k.

Answer 2

5 = k /7.5

find k

Answer 3

multiply both sides of the equation by 7.5;
