The slope is $- 3$ $-3$ .

First, let's write the equation where $y$ $y$ is by itself.

We have $3 x + y = - 2$ $3x + y = -2$ .

To make $y$ $y$ by itself, we need to subtract both sides by $3 x$ $3x$ and we get:

$y = - 2 - 3 x$ $y = -2 - 3x$

There are many definitions of slope, and one of them is rise over run or the change of y over the change of x.

The slope is the value in front of $x$ $x$ , which is $- 3$ $-3$ .

Hope this helps!
