Answer:
[tex]S_{DA}=-11[/tex]
Step-by-step explanation:
From the question we are told that:
The Vertices points for DAN
[tex]D= (2.5,3)[/tex]
[tex]A=(3.2,- 4.7)[/tex]
[tex]N=(-6.9.3)[/tex]
Generally the equation for slope of DA [tex]S_{DA}[/tex] is mathematically given by
[tex]S_{DA}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]S_{DA}=\frac{-4.7-3}{3.2-2.5}[/tex]
[tex]S_{DA}=-11[/tex]
