The equation of variation is a mathematical concept that illustrates how a particular quantity modifies in relation to another. This can occur in three ways: directly (y = kx), inversely (y = k/x), or jointly (y = kxz). Here, 'k' represents the constant of variation. To figure out the equation, you must first determine the kind of variation, calculate 'k' using the provided values, and then replace these values in the formula.
