Definition: To solve a system means to find the points of intersection
Methods for Solving a System:
- Graphing
- Substitution
- Elimination (Linear Combination)
- Determinants
- Augmented Matrices
Types of Solutions
- $l_1 \parallel l_2$ : No solution. Inconsistent
- $l_1 \cap l_2$ : 1 Solution. Consistent, Independent
- $l_1 = l_2$ : $\infty$ Solutions. Consistent, dependendent
