Answer:
(-1-2)/(7-(-3))

Explanation:

The slope of a line passing from (a,b) and (c,d) is given by :-

$\text{slope}=(d-b)/(c-a)$

Given points of a line : (-3,2) and (7,-1)

Substitute a=-3, b=2, c=7, d=-1 in the above formula of slope we get,

The slope of a line containing the points (-3,2) and (7,-1) will be :-

$\text{slope}=(-1-2)/(7-(-3))$
