Answer:
Option H. [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have
[tex]A(12m,m)\ B(18m,6m)[/tex]
Substitute the values
[tex]m=\frac{6m-m}{18m--12m}[/tex]
[tex]m=\frac{5m}{6m}[/tex]
Simplify
[tex]m=\frac{5}{6}[/tex]
