A vertical line has the equation of x = a 
If the vertical line goes through a certain point, as in this case, then the y value is irrelevant. It can be anything. It is the x value that is the one you need to use. 
So the answer is x = 1. This equation has no slope that is defined.
        
             
        
        
        
Based on the hints of distinguishing between <em>radical</em> and <em>non-radical</em> numbers, we have the following lists:
 , , , 2.5, , 2.5, 
- 3.01,  , , , , 
 , - 4.1, 4.01, , - 4.1, 4.01, 
- - 2.5,   , , , 2.5 , 2.5
<h3>How to order numbers from least to greatest</h3>
In this question we must order sets of numbers in ascending order. A hint consists in comparing <em>non-radical</em> numbers with the <em>closest</em> <em>radical</em> numbers whose results are integers. 
In consequence, we obtain the following orders:
 , , , 2.5, , 2.5, 
- 3.01,  , , , , 
 , - 4.1, 4.01, , - 4.1, 4.01, 
- - 2.5,   , , , 2.5 , 2.5

Answer:
30/(2x^2-x)
Step-by-step explanation:
5/(2x-1) * 6/x
Multiply the numerators
5*6 = 30
Multiply the denominatos
(2x-1) *x = 2x^2 -x
5/(2x-1) * 6/x = 30/x(2x-1) = 30/(2x^2-x)
