Answer:
I believe it would be D.
Step-by-step explanation:

The standard form of the equation of a circumference is given by the following expression:
</span>

<span>
On the other hand,
the general form is given as follows:
</span>

<span>
In this way, we can order the mentioned equations as follows:
Equations in Standard Form: </span>
Equations in General Form:


So let's match each equation:
Then, its general form is:
<em><u>First. a) matches 5)
</u></em>

Then, its general form is:
<em><u>Second. b) matches 1)
</u></em>
Then, its general form is:
<em><u>Third. c) matches 3)</u></em>
Then, its general form is:
<em><u>Fourth. d) matches 6)</u></em>
The second choice is correct, but I believe that either its +1/3 ( in the question) or -3y as that will give you the answer of: y=1/3x+6
