please show all work to help me better understand.

Let f(x) = 167 - I The slope of the tangent line to the graph of f(a) at the point (3, 8) is The equation of the tangent line to the graph of f(r) at (3, 8) is y - me + b for m= and b= Hint: the slope is given by the derivative at r = 3, ie. f(3 + h) - f(3) lim h-0 h
