Find the slope of the tangentline to the graph of the given function at the given value of x.Find the equation of the tangent line.

Find the slope of the tangent line to the graph of the given function at the given value of x. Find the equation of the tangent line. y=x4. - 6x +6; x = 1 How would the slope of a tangent line be determined with the given information? A. Substitute values of x into the equation and solve for y. Plot the resulting points to find the linear equation. B. Substitute 1 for x into the derivative of the function and evaluate. C. Substitute values of y into the equation and solve for x. Plot the resulting points to find the linear equation. D. Set the derivative equal to zero and solve for x. The slope of the tangent line is The equation of the line is (Type an equation. Type your answer in slope-intercept form.)
