x>3
 
I hope this helped!! Good luck (:
 
        
             
        
        
        
The two lines intersect at (-3,4) 
-2/3X+2= -2X-2
Add 2X to both sides 
Subtract 2 from both sides 
Divide both sides by 4/3
You get X=-3
Plug in 3 to one of the equations and you’ll see that y= 4
        
             
        
        
        
The question is asking for a fourth of a third.
