Please help. What is the slope for #2?

Answer: -4
Step-by-step explanation:
To find the slope, you want to use the slope formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. You can use any two points to solve. Let's use (-2,3) and (-1,-1).
[tex]m=\frac{-1-3}{-1-(-2)} =\frac{-4}{1} =-4[/tex]
Another way to tell is by looking at the arrows with a -4 written next to it. That also tells you what the slope is.
