Answer:
2y^2 +5y
Step-by-step explanation:
y^2 + 11y - 6y + y^2
Combine like terms
2y^2 +5y
 
        
                    
             
        
        
        
You split the abs val into a pos and neg soln to write
x–5 = 3 and x–5 = –3
x = 8 and x = 2
        
                    
             
        
        
        
from what I remember from what my teacher taught me was that its nonlinear. I'm 98% sure its nonlinear 
I'm am so sorry if I get it wrong. I'm apologizing ahead. if you want you can get the points back I dont mind because I feel bad when I get things wrong but I'm pretty sure its non linear 
 
        
             
        
        
        
You need to rise divided by the run. Another way to put it is 
m = (y2 - y1)/(x2 - x1)
Take your points and plug them in
m = (2 - 9)/(-5 - 3) = (-7)/(-8) = 7/8 is the slope
