name the points
a=(x1,y1) b=(x2,y2)
a=(6,8) b=(9,10)
use the slope formula
[tex]m=\frac{y2-y1}{x2-x1}[/tex]replace
[tex]\begin{gathered} m=\frac{10-8}{9-6} \\ m=\frac{2}{3} \end{gathered}[/tex]answer= The slope is equal to 2/3
a=(9,10) b=(6,8)
using the formula
[tex]\begin{gathered} m=\frac{y2-y1}{x2-x1} \\ m=\frac{8-10}{6-9} \\ m=\frac{-2}{-3}=\frac{2}{3} \end{gathered}[/tex]slope will also be 2/3
