Integers between -4 and 0 are : -3, -2, and -1
        
                    
             
        
        
        
Add the numbers together and divide it by 2. 1.5 + 7.1 is 8.6. Then divide by 2 to get 4.3
        
                    
             
        
        
        
D -2, 4 is in the second quadrant because the -x brings it to the left side and the positive 4 puts it in the upper of the left side which is the second quadrant
