An expression for the cost will be 50+100n, where n is the number of cavities.
        
                    
             
        
        
        
 I'd say an outlier. P is separated noticably from the other points and would not considerably affect the slope of the line
 
        
                    
             
        
        
        
-x+y=3
y=x+3
2x + x + 3 =6
3x + 3 = 6
3x = 3
x = 1
-1 + y = 3
y = 4
2(1) + y = 6
2 + y = 6
y = 4
Solution: (1, 4)
