Answer:
[tex]\displaystyle- \frac{1}{6}[/tex]
Step-by-step explanation:
We will use the slope formula. Let P be point one and Q be point 2.
[tex]\displaystyle \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
[tex]\displaystyle \frac{5-6}{2--4}[/tex]
[tex]\displaystyle \frac{-1}{2+4}[/tex]
[tex]\displaystyle- \frac{1}{6}[/tex]
