You can put this solution on YOUR website! Can you help? x=-5 what is the slope. Thank you! Shelly
--------------
If x = -5, 2 of the points might be (-5,0) and (-5,1)
---
slope = (1-0)/(-5--5) = 1/0 which is undefiined.
---------------
The line is a vertical line (straight up and down).
The slope of any vertical line is undefined.
