Answer:
C
Step-by-step explanation:
 
        
             
        
        
        
The horizontal asymptote of a rational function tells us the limiting value of that function as it approaches infinity.
For a rational function to have a horizontal asymptote of 

then,

The second condition is that, 

Example are given in the graph above.
Here are some other examples,

 
 
        
        
        
Let the number of pepperoni pizzas be x
pepperoni = x
veggie = x - 8    [<span>There were eight fewer veggie than pepperoni]
</span>combo = 3x       [T<span>here were three times as many combo as pepperoni]
</span>
Given that the total Pizza: 112
x + x - 8 + 3x = 112
5x - 8 = 112
5x = 112 + 8
5x = 120
x = 24
x= 24
x - 8 = 16
3x = 72
So there were 24 pepperoni pizza, 16 veggie pizza and 72 combo pizza
        
             
        
        
        

now, a line perpendicular to that one, will have a "negative reciprocal" slope, thus
