12.06.2021 · In symbols, the direct variation formula is y=kx or k=y/x where k is the constant of variation or proportionality constant. A simple problem situation will show clearly the idea of a direct relationship between quantities. Say, a motorist drives along the North Expressway at a constant speed of 80 km per hour. How far will he go in 2 hours?

To write the equation of direct variation, we replace the letter k by the number 2 in the equation y = kx. y=2x. When an equation that represents direct ...
Direct variation A direct variation, also called direct proportion is a relationship between two variables x and y that can be written as y = kx, k ≠ 0. This situation occurs when the ratio of two variables is constant. When y = kx, we say that y varies directly with x. When z = kt, we say that z varies directly with t.
