Answer: −3 over 2
Explanation:
Formula to find the slope of a line that passing through two points (a,b) and (c,d) is given by :-

The given points are : (-3, 2) and (-1,-1)
Then, the slope of the line passing through theses points =

[∵ (-)(-) = (+)]

Hence, the slope of the line shown in the graph

Hence, the correct answer is −3 over 2.
