Question: Need help with this problem If f(x) = 4x - 5x + 6, find f' (4). Use this to find the equation of the tangent

Need help with this problem

If f(x) = 4x - 5x + 6, find f' (4). Use this to find the equation of the tangent line to the parabola y = 4x - 5x + 6 at the point (4, 50). The equation of this tangent line can be written in the form y = ma + b where m is: and where b is
