Question

How do direct and inverse variation differ?

Answer 1

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
