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.
If X = 2 then Y = 8, and so on. What are the values for Y when X = 3? X = 4? Now look at a graph of how Y varies as we change X. As X increases in magnitude, Y increases in a linear fashion. This is called a direct relationship. (In an equation such as Y = -X, the relationship is still direct, although Y decreases as X increases, because X 1 /X 2 = Y 1 /Y 2)
