Hey there!
Use the slope formula:
[tex]\bold{\displaystyle\frac{y2-y1}{x2-x1}}[/tex]
Where
y₂=-12
y₁=-6
x₂=11
x₁=8
Plug in the values:
[tex]\bold{\displaystyle\frac{-12-(-6)}{11-8}}[/tex]
-12-(-6) is the same as -12+6:
[tex]\bold{\displaystyle\frac{-6}{3} =-2}[/tex]
Hence, the slope of the line is
[tex]\boxed{\boxed{\bold{-2}}}[/tex]
Hope everything is clear.
Let me know if you have any questions!
