In order to find a perpendicular line, you need the equation in the form:
So convert your function into the form mentioned above:

=
=
Next, we take the inverse reciprocal of the slope (m is the slope in the equation y=mx+b.
The reciprocal of 15 is 1/15, to invert the number, simply make it the opposite sign that it currently is (positive turns to negative, and vice-versa). Therefore, the slope of the line perpendicular to y=15x-15, is -1/15.
The perpendicular line, now has the equation:
Now, we must solve for b. To solve for b, we simply plug in the x and y values from the point above. (x,y), (6,-5).

Now plug b back into the equation and you have your answer:
