Step-by-step explanation:
1. the same : no solution means lines do not intersect which means they are parallel
2. the same : infinitely many solutions mean two lines overlap so they have same slope
3. different : parallel but not overlapping lines. so slope is same but different y intercepts
4. the same : overlapping lines so slopes AND y intercepts are same
5. different : lines should have different slopes in order to have a solution
