Recall the slope equation [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
We're given 4 different coordinate points, but we only have to use 2.
Let's use (-6, 8) and (-2, 5), since they're the first two points in the graph.
Use [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]:
[tex]\frac{5 - 8}{-2 - (-6)}[/tex]
[tex]\frac{-3}{-2 + 6}[/tex]
[tex]\frac{-3}{4}[/tex]
The slope of the line is -[tex]\frac{3}{4}[/tex]
Good luck! If you need me to explain any of this process in more detail, just ask :))
