    Tangent line to a given curve.

    How would I find the solution to the tangent line to the curve y = 1/(x +4) that passes through the origin?

    Thanks,

    Hi

    Differentiate to find the gradient of the tangent . Then , we know it passes through (0,0) so we can find the equation of the tangent
    using y-y1=m(x-x1)

    ie y-0=(dy/dx)(x-0)
