The slope is usually represented by rise/run, which means the amount of units you go up over the amount of units you go right. If you go down, it would be a negatove rise, and if you go left, it would be a negative run. When you have
![\frac{-}{+}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-%7D%7B%2B%7D)
or a
![\frac{+}{-}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%2B%7D%7B-%7D)
, that would make your slope negative, since your fraction is negative. If you have both negatives or both positives, it would be a positive slope because your answer is positive. In this case, we can take the points (-1,3) and (0,0) to find the slope. There are many ways to do it, but the easiest one for me if you already have a graph is to count how many units or numbers you go up and how many you go left and plug those in to the formula.
It'd be: for the rise (the amount of spaces from y to y) you start at +3 and end at 0, so the rise would be -3. It is negative be cause you are going down, not up like I said before. For the run (amount of spaces from x to x) you start at -1, and end at 0, so you move right 1 space. Your run is 1. This will give you a slope of
![\frac{-3}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-3%7D%7B1%7D)
, which can, of course, be simplified to -3. Your slope is -3.
Good luck in math class!

Answer:
D
Step-by-step explanation:
I'm not the greatest in this subject, but I think that it's D/If the roof leaks, then the ceiling gets damaged because it clearly says that in the statement. It could be all of them, though, but this is my answer. Hope it helps!
