Answer:
Option C. Yes; y=2x
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
so
In this problem
For x=0, y=0
That means ----> the line passes through the origin
<em>Find the value of k</em>
For x=2, y=4
----> 
For x=4, y=8
----> 
The values of k are equal
therefore
The table represent a direct variation
The equation is equal to

1) 2 1/5
2) -1 1/4
3)1 5/8
4)19/30
5)2 1/6
6) ???
7)-8 5/24
8)???
9)6 11/15
10)???
11)???
I couldn’t see the ones with the ??? on them and also all you have to do to get the answer is find the LCD and combine
