The minimum value is the lowest point of a graphed line. The would be the bottom of the "U" shape.
 Looking at the graph you can see that the bottom of the U is touching the horizontal line at x = -5.5, so this would be the minimum value.
The lowest part of the line is at -5.5
 
        
                    
             
        
        
        
The absolute value is |5| = -5
