Theres information missing in the question. There should be one more pair of coordinates
        
             
        
        
        
I believe it would be as following:
x+7>12
Here, x represents the unknown number. The symbol for no less than is greater than.
        
                    
             
        
        
        
-29/6<x<25/6
I'm sorry I can't graph because Brainly won't take my Img. 
But I will tell you that it is a closed circle.
