20.11.2020 · Direct Variation Word Problems – Definition, Formulas, Solved Examples. November 20, 2020 by Veerendra. Direct Variation is an essential concept in Ratios and Proportions. We are providing the important formulas, explanations, and definitions here.
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.
Direct variation word problems may be solved using the following steps: 1) Recognizing the word problem consists of direct variation as exemplified by presence of verbiage listed above; 2) Writing an equation containing known values for both variables resulting in an expression containing only the unknown representing the constant of proportionality;
