The perpendicular line will have the x and y coefficients swapped and one of them negated. We can write the desired line as
  9(x -6) -3(y -4) = 0
where the coordinates of the point of interest are (6, 4).
Dividing by 3, this is
  3(x -6) -(y -4) = 0
  3x -y = 14

An equation for the line of interest is ...
  3x -y = 14
