A normal line to a curve passes through a point P on the curve perpendicular to the line Ay tangent to the curve at P (see figure). Use the following equation and graph to determine 12- an equation of the normal line at the given point and illustrate your work by graphing the curve with the normal line. X 3 ( x 2 + 2) 2 =100xy; (3,1) -12 Write the equation for the normal line. V=
