Direct variation problems are solved using the equation y = kx. In this case, you should use d for distance and f for force instead of x and y. Step 2: Use the information given in the problem to find the value of k. In this case, you need to find k when f = 160 and d = 5.
In a direct variation when the value of one variable increases then the value of another value also increases, when the value of one variable decreases then the value of another variable is also decreases. The general form of the direct variation is y = k x, where k is a constant and x and y are variables. Back to Top.
