Answer:
The slope is 10/5
Explanation:
The slope is the rise over run, or how many it goes up/down over how many it goes left/right.
If you keep adding to -2 all the way until you get 8, you'd get 10, since you'd add 2 to get to 0 and 8 to get to 8
If you keep adding to -5 all the way to 0, you'd get 5.
Hope this helps!
