The line has equation
You want to get the line into a form where x is the slope and b is the place on the y-axis where the line crosses the y-axis.
Divide both sides of the equation by 3 and you get

So, the slope of the line is .
Any line parallel to this line will also have a slope of .
So, we're looking for a line with equation and we need to figure out what b is.
We know that point (0,3) is on the parallel line so we know that when then . So, solve for b:
or .
So, the equation of the parallel line is .
