A perpendicular line has a negated inverted slope. So if I have a slope of 2, I will have a slope of . The general rule for a perpendicular slope is
where is the perpendicular slope
So if m=3 then . Now use the point-slope formula
Plug in m=-1/3 and (,)=(4,3) and solve for y
So this is the perpendicular line through (4,3)
