Answer: -1/2
Step-by-step explanation:
slope is you know rise over run
which means the equation would look like [tex]\frac{y}{x}[/tex], but since there's no graph and line showed up and only have two points given, you should subtract second point and first point (the order doesn't really matter tho), then [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], so
[tex]\frac{-2-(-1)}{-6-(-8)}=\frac{-1}{2}[/tex]
