Practice 4 Part 2 of 3 K Show that the line tangent to the graph of y = x + 4x - 2x at (1,3) is also tangent at ( = 1,1). What is the relationship between the slopes of the tangent lines at (1,3) and ( - 1,1)? A. They are the same. O B. One slope is twice as steep as the other. O C. One slope is the negative of the other. O D. They are perpendicular. What is the equation for the tangent line at (1,3)
