Answer:
undefined
Step-by-step explanation:
Vertical lines never have a defined slope as you can never divide a number by zero
The equation of a line in standard form is:
y
=
m
x
+
b
Where
m
is our slope
b
is our y-intercept
In our case we are only given
x
=
6
x
=
6
is a vertical line therefore the slope is undefined.
