Question

what is the slope of the line 9x - 4 lny =3 that goes through the pt (1/3, 1) ?

Answer 1

ax + by + c = 0

Slope = -a / b

Answer 2

@Yahoo! you misunderstood, it lny there, so its a curve, we are asked to find the slope of tangent at (1/3 ,1)

for that
express the eqn in terms of y
(9x-3)/4 = lny

=>y = e^(9x-3)/4

not find dy/dx

in that put x=1/3 and y=1
