Find the variation constant and an equation of variation where Y varies directly as X and Y=60 when X=10

k=variation constant
y=equation of variation

Still do not understand..please..

  • Algebra -

    If y varies directly as x, it means that

    y = kx

    where k is called the variation constant. That is, y is always some multiple of x. It varies "directly".

    So, we want to find k. To do that, we need to know both x and y. Luckily, they have said that y=60 when x=10. Plug them into the equation:

    60 = k*10
    k=6

    So, now we know that y=6x

    Aha...thank you..
