To find the perpendicular line, of any given line goes like this...
if m (slope) of this given line is 1/3, than we know that the perpendicular line has a slope of -3
Now, to find the equation of this line, we need to find out where it crosses the y-axis... And because we are not given any specific points on where the perpendicular line crosses. We see that the point it pass the y-axis is 0
So... the perpendicular line of 1/3x+2 is -3x
