Example Question #34 : How To Find Out If Lines Are Parallel

Which of the following are parallel to the line ?

Possible Answers:

Correct answer:

Explanation:

Two lines are parallel when they have the same slope. We can determine the slope of a line in the form   by identifying , the coefficient of x.

In this case, a line will be parallel to  if and only if the coefficient of x is 3.

So we find:
