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.
Direct Variation. Words: a line that has a constant âkâ and goes through the origin. Symbols: y = kx, where k is a number (positive or negative) Example: y = 3x. 3 or k is called âconstant of variationâ or âconstant of proportionalityâ Example 1 The height of the water as a pool is being filled is shown in the graph.
