Find a general expression for the slope of a tangent line to the indicated curve. Then find the slopes for the given values of x. Sketch the curves and tangent lines y = 5.5x - 3x x= - 1.5, x =0.5, x =3 What is the general expression for the slope of a line tangent to the curve of the function y = 5.5x - 3x at the point P(x,y)? man (Simplify your answer ) The slope at x = - 15 is (Simplify your answer.) The slope at x = 0.5 is (Simplify your answer ) The slope at x = 3 is (Simplify your answer.) Sketch the curve of y = 5.5x - 3x and the line tangent to the curve at x = - 1.5.
