If you mean “13 more than the product 4 and a number, n” 
then the answer is B
the word product means multiply 
and 12 more means adding 12 to the product
        
                    
             
        
        
        
Your answer would be option B. 2y² - y - 6 = 0. This is because if you were to substitute x = y² - 1 into the equation 2x - y = 4, you would get 2(y² - 1) - y = 4, which expands into 2y² - 2 - y = 4, and then simplifies to 2y² - y - 6 = 0.
I hope this helps!
        
                    
             
        
        
        
yes it is always coplanar with two intersecting lines.
 
        
                    
             
        
        
        
The correct answer is C. A linear equation is written in y=mx+b, which this equation can be. y=3-4x is the same as y=-4x+3, which is a linear function.
