Direct and Inverse Variation: Formulas and Applications

WebThe sign “ ∝ ” is read “varies as” and is called the sign of variation. Example: If y varies directly as x and given y = 9 when x = 5, find: a) the equation connecting x and y. b) the value of y when x = 15. c) the value of x when y = 6. Solution: a) y ∝ x i.e. y = kx where k is a constant. Substitute x = 5 and y = 9 into the equation:
