When two functions vary inversely with each other, they are usually in the form y = k / x, where k is the constant of proportionality.
To find the equation for the inverse variation, find the constant of proportionality. Do that by substituting the values for x and y into y = k / x and solving for k.
y = k / x
4 = k / 6
24 = k
Answer:
The constant of proportionality is 24. The equation for the inverse variation is y = 24/x.
