 Answer:
6
Step-by-step explanation:
First distribute 
4 times -2 = -8
4 times -4 = -16 
12(-8/-16) 
-8/-16 = 0.5 
so 12(0.5) = 6 
 
        
             
        
        
        
The average cost represents the slope of the line of the graph.
Increasing the slope of the graph increases the steepness of the line.
Therefore,
increasing the average cost of gas from $1.50 to $2.20 will increases
the steepness of the line. (i.e. the line becomes closer to the vertical
line).
