Parallel Lines and Points of Intersection

#LinearAlgebra #VectorGeometry #2DGeometry We dive into the notion of parallel lines in this video. After formulating two conditions for two lines being equal, we prove that there is a unique line containing any two given points in the real plane, and any two non-parallel lines meet at a unique point. We also do an example on how to find the point of intersection of two non-parallel lines given in vector form. This video is part of the series Linear Algebra.
