I need help on this question ASAP

Slope of a tangent line PART 1. Using the definition of derivative, f'(x) = lim f(x + h) - f(x) , find the slope of the tangent to the curve at the given point. h-0 h f(x) = 8r' - 8r +3;1 = -12 The slope of the tangent to the curve at c = -12 is Enter a numeraical value for the slope. PART 2. The equation of the line tangent to the curve at c = -12 is Type answer in form y = max + b
