Sagot :
m = [tex]\frac{Y_{2}-Y_{1}}{X_{2}-X_{1}} [/tex]
= [tex] \frac{2-4}{1-3} [/tex]
= [tex] \frac{-2}{-2} [/tex]
= 1
= [tex] \frac{2-4}{1-3} [/tex]
= [tex] \frac{-2}{-2} [/tex]
= 1
[tex]Slope= \frac{Y_{2}-Y_{1}}{X_{2}-X_{1}} \\ \\ Slope= \frac{2-4}{1-3} \\ \\ Slope= \frac{-2}{-2} \\ \\ \boxed{\boxed{Slope=1}} \\ \\ Hope\ it\ Helps:) \\ Domini [/tex]
