How do direct and inverse variation differ? Algebra Rational Equations and Functions Inverse Variation Models 1 Answer seph Oct 25, 2014 When two things x and y vary directly, it means that as x goes larger, y also goes larger. And when x goes smaller, y also goes smaller On the other hand, when two things u and v vary inversely, it means that as u goes larger, v goes smaller. And when u goes smaller, v goes larger Answer link Related questions What are Inverse Variation Models? How do you solve inverse variation problems? How is inverse variation used in everyday life?
