Question

how do you find slope from two slopes?

Answer 1

I'm not sure I understand the question. Did you mean the slope from two points?

Answer 2

yes

Answer 3

If you have two points:
\[(x _{1}, y _{1}), (x _{2}, y _{2})\]
then the slope between them is given by:
\[(y _{2}-y_{1})/(x _{2}-x _{1})\]
