Nvm, I think I found it.

Just to check, is it y = 19/2 - x/4 ?

OpenStudy (ranga):

Find the slope of the tangent to y = x^2 + 5 at (2,9) The slope of the normal line will be the negative reciprocal of the slope of tangent. Knowing the slope and a point you can find the equation of the normal line.
