Determine if two lines are parallel to each other


	Algebra I: Determine if two lines are parallel to each other

In this mini-lesson, you'll learn how to determine if two lines are parallel. Parallel lines are distinct lines lying in the same plane - they never intersect each other and have the same slope. If two lines y₁ = m₁x₁ + c and y₂ = m₂x₂ + c are parallel, then m₁ = m₂ because m₁ and m₂ represent the slopes of the two lines. For example, 6y = 3x + 30 and 2y = x + 4 are parallel lines with slope of 1/2.
