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.
A relationship between two variables can be described by an equation or a formula. This relationship can be linear, quadratic, square root, or almost any other type of function you can think of. We will focus here on a linear relationship between two variables where one is a constant multiple of the other. This is a special relationship called direct variation. In general, we say that y varies directly as x if there is a constant k so that the equation is true. When graphed, the constant k will be the slope of the line, y = mx + b.
