The expression for the slope of line passing through two points are :

$\text{ Slope=}(y_2-y_1)/(x_2-x_1)$

In the given question:

Two points are : (6,9) & ( 7,1)

$\begin{gathered} (x_1,y_1)=(6,9) \\ (x_2,y_2)=(7,1) \\ \text{ Slope=}(y_2-y_1)/(x_2-x_1) \\ \text{Slope = }(1-9)/(7-6) \\ \text{Slope}=(-8)/(1) \\ \text{ Slope = (-8)} \end{gathered}$

Slope = (-8)

Answer : A) - 8
