The correct answer is


3y+x=0

If we write this solution in another form , it can have


y=(-1)/(3)x\text{ or 3y=-x}

This is working;


\text{Slope}=(y_2-y_1)/(x_2-x_1)=(0-1)/(0--3)=(-1)/(3)

The equation of the line is;


\begin{gathered} y-y_1=slope(x-x_1) \\ y-1=(-1(x--3))/(3) \\ 3(y-1)=-1(x+3) \\ 3y-3=-x-3 \\ 3y=-x \\ y=(-x)/(3) \end{gathered}
