Dear LINTA


equation of parabola   y2=4*6*x


                       a =6


equation of given equation  3x-5y+k=0


                                                or   y = 3x/5  + k/5


                                  m = 3/5    and  c= k/5


condition for tangency   C =a/m


                                           k/5  = 6/(3/5)


                                           k = 50

										 y2=4*6*x


a =6

equation of given equation 3x-5y+k=0

or y = 3x/5 + k/5

m = 3/5 and c= k/5

condition for tangency C =a/m

k/5 = 6/(3/5)

k = 50
