Answer:

-1/3

Step-by-step explanation:

There's a formula that I'll use to find the slope - it's called the slope formula.


\sf{m=(y_2-y_1)/(x_2-x_1)}

Plug in the data:


\sf{m=(8-4)/(-4-8)}\\\\\sf{m=(4)/(-12)

Simplify:


\sf{m=-(4)/(12)}


\sf{m=-(1)/(3)}

Hence, the slope is negative one-third.
