Question 147890: I am trying to find the slopeof x= -6. When graphing, x is always -6 no matter what y may be. So, I have a vertical line at -6 on the x axis. To me, this slope is undefined or does not exist at all. Am I on the right track?
Thank you for your time and help on this.

Yes.
If you look at the equation of slope,
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
Since x%5B2%5D=x%5B1%5D, then the denominator is 0 while the numerator is not.
So, you're correct, the slope is either undefined or infinite.

You are correct.
The slope of a vertical line is "undefined".
