Answer: -5
Step-by-step explanation:
The slope of a line passing through (a,b) and (c,d) is given by :-
[tex]\text{Slope}=\dfrac{d-b}{c-a}[/tex]
Then the slope of the line AB contains points A (3, −2) and B (1, 8) will be :-
[tex]\text{Slope}=\dfrac{8-(-2)}{1-(3)}\\\\\Rightarrow\text{Slope}=\dfrac{10}{-2}-5[/tex]
Hence, the slope of the line AB contains points A (3, −2) and B (1, 8) = -5
