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.
This is done by substituting the values of x and y into the equation for a direct varition and then solving for k. Example 1 will describe show how to find k. Example1: The point (2, 8) is a point on the graph of a direct variation. Find the constant of variation. We start with the equation: y = kx. The point (2, 8) tells us that x = 2 and that y = 8. Next, substitute these values into the equation to get: 8 = 2k.
