Prime polynomial cannot be factorized into the product of two polynomials of lesser degree. Example: x2+x+1. Good luck.

Answer:   4/9</h3>
==============================================
Work Shown:

The idea is that when we subtract 10x and x, the infinite decimal pattern (the 4s that go on forever) will cancel. That leads to 9x = 4 which solves to x = 4/9
 
        
        
        
Answer:
The coordinates are (-8,7).
 
        
                    
             
        
        
        
If you are trying to find the slope using only these two points then you should first take note of what your X and Y values are. For instance, 12 & 11 are your X values and -18 & 12 are your Y values. Knowing this you can now find your slope by doing y2-y1/ 
x2-x1. You will get the fraction -30/1 or -30 which is your slope. Hope that made sense!
