Problem #5: (a) If an equation of the tangent line to the curve y = f(x) at the point where a = 9 is y =10x-2, find f(9) and f'(9). (b) If the tangent line to y = f(x) at (-1, 8) passes through the point (7, 8), find f(-1) and f'(-1). Problem #5(a): Problem #5(b): separate your answers with a comma. (Your answers MUST be in the correct order.) Enter your answer symbolically, c in these examples separate your answers with a comma.
