Let f(x) = 5.7x² - 8x. Use the difference quotient and h = 0.001 to estimate the slope of the tangent line at x = 6. What is the slope (round your answer to one decimal place)? m What is the y-value at x = 6? f(6) = Use the above (rounded) slope and y-value to write the equation of the tangent line to the graph of f(x) at x = 6. Write your answer in mx + b format. Y
