Answer:
4
but I think you wrote the question down wrong so its likely
4/5
Explanation:
(3,-1) and (2,-5)
slope is:
change in y
----------------
Change in x
look at the y's -1 and -5. The change or distance between them is -4
look at the x's 3 and 2. the change or distance between them is -1
so the slope is -4/-1 or 4
Since that not one of the answer I suspect you wrote it down incorrectly
because
if the it was (3,-1) and (-2,-5) it would be -4/-5 or 4/5
