Answer:

\huge \boxed{ \boxed{ -  \frac{1}{2} }}

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\

From the question we have

m =  \frac{6 - 8}{12 - 8}  =  -  \frac{2}{4}  =  -  \frac{1}{2}  \\

We have the final answer as

-  \frac{1}{2}  \\

Hope this helps you
