Find the slope(6,8) and (9,10)
USPshnik [31]

name the points

a=(x1,y1) b=(x2,y2)

a=(6,8) b=(9,10)

use the slope formula

m=\frac{y2-y1}{x2-x1}

replace

\begin{gathered} m=\frac{10-8}{9-6} \\ m=\frac{2}{3} \end{gathered}

answer= The slope is equal to 2/3

a=(9,10) b=(6,8)

using the formula

\begin{gathered} m=\frac{y2-y1}{x2-x1} \\ m=\frac{8-10}{6-9} \\ m=\frac{-2}{-3}=\frac{2}{3} \end{gathered}

slope will also be 2/3
