Tangent Line and Average Value

Please choose the correct answer:

Q#11)
The average value of f(x) = 1/x on the interval [2, 8] is

(ln 2)/3
6/5
(ln 6)/6
(ln 4)/2
0
1
none of these

Q#1.
Find the equation of the tangent line to y = ln x at the point where x = 2.
y = x/2 - 1 + ln 2
y = x/2 - 1 + 2 ln 2
y = x/4 - 1 + ln 2
y = x/4 - 1 + 2 ln 2
y = x/8 - 1 + ln 2
y = x/8 - 1 + 2 ln 2
y = x/8 - 1 + 3 ln 2
none of these
