    Help i really don't understand Direct and Inverse Proportion?...
    Direct proportion ... If one variable doubles so does the other ... The fraction a/b is constant


    Inverse proportion ... If one variable doubles the other halves ... The product ab is constant

    Where a and b are the variables

    Direct: y = kx
    Inverse: y = \frac{k}{x}

    Where k is a constant in each case.

    You're welcome. The definitions TenOfThem gave were also correct, but I felt that mine were probably easier applied to your question.
