try

anonymous · Answer

yea i figured thats what u meant

anonymous · Answer

Does anyone know this?!?! hahaha

anonymous · Answer

Alright since the equation of a slope is (y2-y1)/(x2-x1) and x=-9 is a vertical line, you will end up with a 0 in the denominator. This will make the slope undefined

anonymous · Answer

Okay. how in the world did u learn this crap! its so hard!

anonymous · Answer

It's actually quite simple. "x=" equations are usually undefined and "y=" equations are usually 0

radar · Answer

Yes, division by 0 is undefined.  If x doesn't change the the change in x is 0, so slope being the change in y divided by the change in x would also be undefined as change in x is 0

I had thought I had made that clear.  Sorry about that.
