If m varies when n varies directly, or m varies directly with n, we call the relationship between them the direct variation (正变关系).If m varies when n varies inversely, or m varies inversely with n, we call it the inverse variation (逆变关系). Direct variation: m=k⋅n⟺mn=korn...

Frequently Asked Questions How do you find the direct variation? Given a point (a,b), the constant of variation is the ratio of the two points given: k=a/b. Once this value is known, the direct variation is then y=kx where x is the input variable and y is the output variable. ...
