You can put this solution on YOUR website! You write this proportion like this:
Where k is the constant of proportionality.
First, you need to find the value of k and you can do this because you are told that y = 8 when x = 2.5, so you substitute these values of y (8) and x (2.5) into the above equation and solve for k.
Multiply both sides by 2.5
You can rewrite the first equation with the value of k included.
Now solve the problem of finding the value of x when y = 2 by substituting 2 for y in the last equation.
Multiply both sides by x Finally, divide both sides by 2. This is the answer.
