Infinite Many Solutions - Lines Overlap; No Solution - Lines are Parallel; Graphing Systems (Part 2)

In this video Mr. Dobrescu explains step by step how to graph systems of linear equatuons when there are Infinite Many Solutions - Lines Overlap; and No Solution - Lines are Parallel; Finally, Mr. Dobrescu explains that if the Lines Intersect, there is one solution; If the Lines Overlap, there are infinite Many Solutions; and If the Lines are Parallel, there is No Solution.
