The slope is undefined (infinitely steep).

Explanation:

For #(x_1;y_1) and (x_2;y_2)#

#(6,-10) and (6,14)#

The equation for a line is #(y_2-y_1) =m(x_2-x_1)#

Which leads to #m = (y_2-y_1)/(x_2-x_1)#

So, substituting

# m= [14-(-10)]/(6-6)#

#m = 24/0 = ∞#

The line is vertical, the slope is undefined, or infinity

That means the line belongs to family of line x=constant,
in this case, #" " x=6#
