ok so i got the tangent lines of the two points,
point A(4,3) y=4/3x-25/3
point B(4,-3) y=-4/3x+25/3
now i just need help finding the normal lines...thanks...

The normal line to a curve at a point is perpendicular to the tangent line at that point.
Find the equation of the normal line to this circle at Point A.
y(x) =
Find the equation of the normal line to this circle at Point B.
y(x) =
(d) At what point do the two normal lines intersect?
