First, let's simplify the inequality

The graph looks like this:
Notice that the white dot is placed above the -6, it is important to include it like that.
Now, as an interval:
wait do what? im confused
Answer:
<h2>y = 3x + b where b is any real number</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
We have the equation: 
Parallel lines have the same slope. Therefore the equation of the lines that are parallel to the given line if in form:

where b is any real number.
