At what point does the normal to y = 1 + 3x + 2x2 at (1,6) intersect the parabola a second time? ( ) The normal line is perpendicular to the tangent line. If two lines are perpendicular their slopes are negative reciprocals - i.e. if the slope of the first line is m then the slope of the second line is -1/m
