slope = - 
calculate the slope m using the gradient formula
m= (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (- 3, 6)
m =  =
 =  = -
 = - 
 
        
                    
             
        
        
        
Turn the feet into meters 1 meter = 100cm and if there is 12cms in a foot than divide 100cm by 12cm and you get 8.3ft
        
             
        
        
        
Answer:
search in anywhere
Step-by-step explanation:
or do it in calculator 
or ask from your teacher
ans : A) y= 0.25x + 3
B) y= 0.25x - 4.5
C) y= 4x + 18
D) y= 4x - 42
 
        
             
        
        
        
The answer would be “undefined”
