5 examples of what you find slope to be

I can think of horizontal, vertical, increasing (positive) and decreasing (negative), but I can't think of a fifth example.

Since this is not my area of expertise, I searched Google under the key words "5 examples of what you find slope to be" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
