Direct Variation

Launch

Subject: Math

Direct variation is the relationship between two variables in which one is a constant multiple of the other. In other words, we can say when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).
