Answer: B. 2
Explanation:
The slope of a line passing through two points A(a,b) and B(c,d) is given by:_

From the given graph , it can be seen that the line is passing from (2,2) and (-1,-4)
Then , the slope of the line passing through the points (2,2) and (-1,-4) will be :_

Hence, the slope of the given line =2
