(4,6)(-2,8)Formula:

$\begin{gathered}\\ \sf\longmapsto m = \frac{ y_{2} - y_{1}}{ x_{2} - x_{1} } \end{gathered}$

x1=4y1=6x2=-2y2=8

$\begin{gathered}\\ \sf\longmapsto m = \frac{8 - 6}{ - 2 - 4} \end{gathered}$

$\begin{gathered}\\ \sf\longmapsto m = \frac{2}{6} \end{gathered}$

$\begin{gathered}\\ \sf\longmapsto m=\cancel{\dfrac{2}{6}}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto ⚘m=3\end{gathered}$
