Calculus help please
Sorry to be a burden, but I've asked pretty much everyone I know and nobody seems to know how to do this.
The question is: "If f and g are functions whose graphs are shown and if h(x) = f(x)/g(x), then find h'(5).
Linked below is the graph. Sorry for the potato quality.

Ninja posted. That really helps, thanks!
h'(x)= (f'(x)g(x)-g'(x)f(x))/g(x)^2
f'(5)=slope of f at x=5
g'(5)= slope of g at x=5
then use f(5) and g(5)
plug into above formula
use quotient rule to find h'(x), then the graphs tell you enough to find h'(5)
