**Damon**, Wednesday, July 9, 2014 at 7:22pmdy/dx = 6x d/dx [ln(x+4)]+ 6 ln(x+4)

= 6 x /(x+4) + 6 ln(x+4)

so at x = 2

dy/dx = slope = m = 12/ln(6) + 6 ln (6)

but ln (6) = 1.79

so use that to find the slope m

then we have

y = m x + b and we know m

find y at x = 2

y= 12 (1.79) = 21.5

so use that

21.5 = 2 m + b

we know m, solve for b

the end
