Which two options could be the next step in simplifying this expression?

 

27 + (3 + 41)
  
 
 

 
 

  

  A. 
  27 + 44 (use order of operations)   
   

 
 

  

  B. 
  30 + 68 (use the distributive property)   
   

 
 

  

  C. 
  30 + 41 (use the associative property)   
   

 
 

  

  D. 
  68 + 30 (use the commutative property)

point slope equation is y- y1=m(x-x1)

m = slope or -5.

the y1 is your y value in the point (-4,9)

 y1=9

x1 = -4 ( the x value in the point )

When you plug in the value it should look like this:
$$y-9=-5(x-(-4) )$$

Two negatives equal a positive so your final answer is:
$$y-9=-5(x+4 )$$
