Answer:
We can solve this question using the slope equation which is y2-y1/x2-x1
If you use that formula and sub in the coordinates
-4 - 5 / -1-2
-9/-3
= 3
The slope should be 3/1 
 
        
                    
             
        
        
        
What you want to first is substitute the numbers in for the variables in the equation 
Since b= -5 , we will plug it in for -b
-5 + c = -13x 
Now plug in -8 for c 
-5 + (-8) = -13x
Add the numbers on the left side, which gives you -13. 
-13 = -13x 
Lastly, divide both sides by -13x, which will give you 1.
So x = 1
        
             
        
        
        
Answer:
ok and thank you for point 
 
        
             
        
        
        
5, and -5 because a negative times a negative equals a positive
        
                    
             
        
        
        
W = 2. Don’t listen to the other guy!
