The slope is -3.
Finding slope can be easy if you just remember that the formula is set up as y=mx+b.

If you have trouble remembering which place the slope is, trying thinking about skiing or sledding; you can only sled or ski down a Mountain slope. Mountain starts with M.
M=slope.
Hope this helps :)
