Essential Questions:

1.  The graphs of the systems of two linear equations in two variables can show the number of solutions to the system.

2.  Systems of equations in two variables can be solved using graphing, substitution, or elimination (linear combinations).

3.  The solution to a system of linear inequalities is the region of intersection of “Half-Planes”.

4.  Parallel lines indicate no solutions, overlapping lines (Equivalent lines) indicate infinite solutions, and non-parallel lines indicate one solution to a system of linear equations.
