Thread: 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)

Thanks.
