Identify the slope of the line shown in the graph below:  slope = -1 
Slope = 0
Slope = undefined 
Slope = 1
                                             
                                          
                                          
                                        
											 
											It's a vertical line. The slope of vertical line is undefined.
The equation of a vertical line is x = a (a - any real number).
