Hey guys, im scratching my head on this one... can you give me a nudge in the right direction...

Find the eqn of the tangent line to the functions given below (write eqn of tangent line in y-y1 = m(x-x1) format):

a) y = f(x) = 1/x when x = 2.

b) y = f(x) = sqrt(2x+4) when x = 6.

Thanks in advnace!
