You'll need to find your slope percent first. Take your intended rise (or more accurately, your drop) of 1.5' and convert it to a percentage of your run. In this case it's 1.5/11.5 for a slope percentage of 13%.
Now plug it into this simple trigonometric formula:
Degrees = Tan-1(Slope Percent/100)
Mathematically, that formula now looks like this:
Answer is 7.41 degrees.
Hope this helps.
