The video tutorial explains how to determine if two given lines are parallel by calculating their slopes. The teacher introduces the problem, defines the equations of the lines, and explains the concept of parallel lines. The slopes of both lines are calculated using the formula -a/b, and since the slopes are equal, it is concluded that the lines are parallel.
