Answer: [tex]-\frac{1}{3}[/tex]
Step-by-step explanation:
The equation used to find the slope of the line with two give points and is:
[tex]m=\frac{Y2 - Y1}{X2 - X1}[/tex]
If the points are and
, we only have to substitute them in the equation:
[tex]m=\frac{4 - 5}{2 - (-1)}[/tex]
[tex]m=\frac{-1}{2+1}[/tex]
Hence, the slope is:
[tex]m=-\frac{1}{3}[/tex]
