Perpindicular lines are found by taking the negative reciprical of the slope of the line. For example if we are given Y=4x+5, we know the slope of the perpindicular line is -1/4. Now we need to find the y intercept. The equation of our line is now
Y= -1/4x+b, where b= the y intercept. All of these lines will be perpindicular to the original equation. We can solve for b if we know a point which the line passes through. For example, if we are given that this point passes through (1,1) we plug this in to get 1= -1/4 + b and solve for b. Now apply this to your original question

There's a lot. They all have a slope of -1/3, though.
To get the perp. slope, flip the given slope and add a negative sign.
All lines of form y = (-1/3)x + b work.
