Eleanor tried to find all the equations of vertical lines tangent to the curve given by 3x2 + 24x - y2 + 2y = -44. This is her solution: Step 1: Finding an expression for dy dx dy y - 1 dx 3(2 + 4) Step 2: Forming a system of equations. 3x2 + 24x - yz + 2y = -44 3(2 + 4) =0 y- 10Step 3: Solving the system. There are no solutions to the system of equations, so there are no vertical lines tangent to the graph. Is Eleanor's solution correct? If not, at which step did she make a mistake? Choose 1 answer: A The solution is correct. B Step 1 is incorrect. c Step 2 is incorrect. D Step 3 is incorrect
