Please help with explanation!

At what point does the line normal to the graph of y = @ - 2 - cat (1, -2) intersect the parabola a second time? Hint: 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
