Answer:
(B)(negative 2) (4) 
Step-by-step explanation:
The arrow on the number line ended at negative 8 (-8).
Given the options:
(A) (negative 3) (4) =(-3)(4)=-12
(B)(negative 2) (4) =(-2)(4)=-8
(C) (2)(4)=8
(D)(3)(4)=12
The expected product is -8 since that is where the arrow ended. Therefore, the product that is modeled by the number line is that which gives a result of -8. The correct option is B.
 (B)(negative 2) (4) =(-2)(4)=-8
 
        
                    
             
        
        
        
You can tell based off the translation of graphs. 
Vertical:
y=f(x) + k : graph shifts k units up
y=f(x) - k : graph shifts k units down
Horizontal: 
y=f(x - k) : graph shifts k units right
y= f(x+k) : graph shifts k units left
        
             
        
        
        
This equation simplified would be 
-y(-5y+6)
 
        
                    
             
        
        
        
By radical do you mean the square root symbol?
