Answer:
To know if these lines are parallel, you just have to look at the slope. In this case they are not.
Explanation:
The slope is the number in front of your x. So for the first formula the slope is 3 and for the second one it is 1/3. The slope tells you in which direction the line goes, so if they are the same, that means that the lines are parallel. In this case the slopes are not the same, so the lines are not parallel.
