Answer:
[tex]\textsf{A.} \quad \textsf{The slope of the line is }\boxed{\dfrac12}[/tex]
Step-by-step explanation:
[tex]\textsf{let}\:(x_1,y_1)=(12,0)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(2,-5)[/tex]
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-5-0}{2-12}=\dfrac12[/tex]
[tex]\textsf{The slope of the line is }\boxed{\dfrac12}[/tex]
