Step-by-step explanation:
0.09w + 1.8 = 0
0.09w = 0 - 1.8
0.09w = - 1.8
0.09w ÷ 0.09 = - 1.8/ 0.09
w = - 20
 
        
             
        
        
        
Answer:
2
Step-by-step explanation:
We can use 2 points to find the slope
m = (y2 -y1)/(x2-x1)
Using ( 0,1) and (1,3)
     = (3-1)/(1-0)
    = 2/1
   = 2
 
        
                    
             
        
        
        
Answer:
y = mx + b. When b ≠ 0, the relationship between x and y is nonproportional.
