The slope of a vertical line is undefined.
  
  
 
 
        
             
        
        
        
Answer:
4 days
Step-by-step explanation:
If he consumed 6 liters in two days, that would mean he would have consumed 3 liters per day. You would divide 12 by 3, since he drinks 3 liters per day, and after 4 days, he would have consumed 12 liters.

Answer:
y + 12 = -  (x - 2)
(x - 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y = 3x is in the form y = mx with slope m = 3
Given the slope of a line m then the slope of a line perpendicular to it is
 = -
 = -  = -
 = - 
Hence
y - (- 12) = -  (x - 2), that is
(x - 2), that is
y + 12 = -  (x - 2) ← in point- slope form
(x - 2) ← in point- slope form
 
        
             
        
        
        
The pattern is that it multiplies the previous term by 4. So 2 x 4 is 8, 8 x 4 is 32, 32 x 4 is 128 and so on and so forth. 
128 x 4 is 512. This is your next term
512 x 4 is 2048. This is the next term after that.
2048 x 4 is 8192. This is your final term. 
I think we just figured out how the game 2048 works :P
