The slope is not defined.

The points are :
$(3,-6) = color(blue)(x_1,y_1$

$(3,-9) = color(blue)(x_2,y_2$

The slope is found using formula:

slope $=(y_2-y_1)/ (x_2-x_1)$

$=(-9 - (-6))/ (3-3)$

$=(-9 +6)/0$

$=-3 /0$ which is not defined

A vertical line does not have a slope, since it does not exist it is not defined.
