I worked them out separately if I'm correct, then the order is:
x+5y=-2
x+5y=4 These are Inconsistent
y=3x+4
-2x+y=4 These are Consistent independent
3x+y=4
-6x-2y=-8 These are coincident
Inconsistent lines=No solution
Coincident lines=exactly on top of each other
Consistent Independant= Solution, as they cross each other.
~Hope this helps!

Answer:
First table
Step-by-step explanation:
We have to find the set of value which could be from a direct proportion.
We know that
Direct proportion :
When x is directly proportional to y


Where k=Proportionality constant

K remain constant when x and y are in direct proportion
From first table




When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.
From second table
not ]define

It is not direct proportion because k does not remain constant.
From third table


It is not direct proportion because k does not remain constant.
