[I attached a picture that might help show you]
The lines do
 NOT Intersect.
 
        
        
        
X would be equal to 0 while y would be equal to -1
-20(0)+6(-1)=-6
-10(0)-4(-1)=4
        
             
        
        
        
Answer:

Step-by-step explanation:
Using the Foil method 
you multiply x times x and get  
 
Then you multiply -4 times X and get -4x
Then you multiply -3 times X and get -3x 
then you add -4 and -3 together and get -7x
Lastly you multiply -4 and -3 and get 12 
And there you have it
