Using the definition of the slope of a tangent line to a curve at a specific point x=a find the equation of the tangent line to f(x)= 2/(x+3) at the point x=0 and find the equation of the normal line (perpendicular to the tangent line) at the same point.

Question

anonymous · Answer

So i got the equation of the line to be -2/9x+2/3 which i am pretty confident with. Correct me if i'm wrong though. I just don't know how to go about finding the normal line.
