Answer: -3
Step-by-step explanation:
The slope of a line passing thorough two points (a,b) and (c,d) is given by :-
[tex]m=\dfrac{d-b}{c-a}[/tex]
From the given description, we observe that the line is passing through (1,-1) and (-1,5).
Then , the slope of the graph passing through (1,-1) and (-1,5) will be :
[tex]m=\dfrac{5-(-1)}{-1-1}\\\\\Rightarrow\ m=\dfrac{5+1}{-2}\\\\\Rightarrow\ m=\dfrac{6}{-2}=-3[/tex]
Hence, the slope of this graph= -3
