Answer:
[tex] \huge \boxed{ \boxed{ - \frac{1}{2} }}[/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
From the question we have
[tex]m = \frac{6 - 8}{12 - 8} = - \frac{2}{4} = - \frac{1}{2} \\ [/tex]
We have the final answer as
[tex] - \frac{1}{2} \\ [/tex]
Hope this helps you
