To convert it into standard form (Ax + By = C), we'll want to move all the terms to the left-hand side of the equation:

3x + y + 9 = 0

So, the correct equation in standard form is indeed 3x + y + 9 = 0.

We're given the following line:

$\bf{y=-3x-9}$

This is standard form:

$\sf{Ax+By=C}$

In order to convert the given equation to standard form, add 3x to both sides:

$\sf{y=-3x-9}$ {write the equation}

$\sf{y+3x=-9}$ {subtract}

$\sf{3x+y=-9}$ <- our equation
