21 is 42% of 50. To do that, you divide 21 by 50, you get .42. You then multiply .42 by 100 to get your answer. 
        
                    
             
        
        
        
The slope is (8-2)/(0-2)=-3
the y intercept is 8
the equation is y=-3x+8
the area to the left is shaded, and the line is solid, so y

-3x+8
 
        
        
        
The answer is 882 because if you divide 882 by 9 you get 98 and 98 time 9 is equal to 882 so therefore 882 is divisible by 9
