Choice A is one of the answers. Nice work. This is because x+x+x turns into 3x.
Choice D is the other answer because 2(x+1) + x = 2x+2+x = 3x+2. You can find this through trial and error. Or you could graph y = x+x+x+2 and y = 2(x+1)+2 to find that they are the same exact identical diagonal line. A non-graph approach would be to set up a table of values to see that the two tables are identical. 
 
        
                    
             
        
        
        
7.8 x 10^7
I don’t know how to explain it but it’s right
 
        
                    
             
        
        
        
The best and most correct answer among the choices provided by your question is the the first choice. We can conclude from the figure you specified that the "<span>Points are graphed at negative 3 comma 2 and negative 1 comma negative 1". </span><span>I hope my answer has come to your help.

D, because the will not intersect i believe
        
             
        
        
        
Theres a saying: Dividing fractions dont ask why, just flip the second and multiply. 
so a/b / c/d = a/b * d/c 
-8/2 * -3/6
1. cross - cancel common factor 2
4/2 * -3/3
2. Multiply
-4(-3)/ 2*3
3. multiply numbers 
--12/2*3
- -12/6
4. Apply fraction rule -a/b=- a/b
=-(-12/6)
5. divide 
= -(-2)
6. Apply rule -(-a)=a
=2
 Your answer would be 2
