01 - Direct Variation and Proportion in Algebra - Part 1 (Constant of Variation & More)

In this lesson, you will learn about direct variation in algebra. Two variables vary directly with one another when as one variable increases the other variable also increases, and vice versa. The constant of variation is the factor that governs how much each variable varies with respect to the other variable. These variables are then said to be proportional to one another.

Many equations in physics and engineering feature direct variation such as Newton's 2nd law of motion, circumference of a circle, and many more.
