 Question 401989: tell whether each equation represents direct or inverse variation: y=80x xy=80 y=80/x y/x=80Answer by richard1234(5390)   (Show Source): You can put this solution on YOUR website!The first and fourth equations are equivalent, and they represent direct variation because when x increases, y also increases by the same ratio. The second and third equations are equivalent and they represent inverse variation because when x increases, y decreases (and vice versa).
