Consider the function and the value of
a. f(x)=(-3)/(x-1), a=4. Use m_(tan)=\lim_(h->0)(f
(a+h)-f
(a))/(h) to find the slope of the tangent line. m_(tan)=f^(')
(a). Find the equation of the tangent line to the graph of f at the point
(a,f
(a)). Which of the following options correctly represents the equation of the tangent line?

A. y = -3x + 13
B. y = -3x + 10
C. y = 3x + 13
D. y = 3x + 10
