is this right??
use the limit process to find the slope of the graph of the function at the specified point.
f(x)= (sqroot of (x + 10)), at (-1, 3)
f(a)= f(x) - f(a)/x-f(a)
Lim as x-> -1 = sqrt of (x + 10) - sqrt of (-1 + 10)/ x- (-1)
Lim as x-> -1 = sqrt of (x + 10) - sqrt of (9) / x - (-1)
Lim as x-> -1 = sqrt of (x + 10) - 3 / x + 1
thats as far as i could go...
so is that the slope? or do i need to do nething further?

Homework Equations
f(a)= f(x) - f(a)/x-f(a)
The Attempt at a Solution
Lim as x-> -1 = sqrt of (x + 10) - sqrt of (-1 + 10)/ x- (-1)
Lim as x-> -1 = sqrt of (x + 10) - sqrt of (9) / x - (-1)
Lim as x-> -1 = sqrt of (x + 10) - 3 / x + 1
