4. READ This lesson extends what you know about graphing inequalities and systems of equations to solving systems of inequalities. A system of two linear inequalities divides the plane in to 4 parts:  Points that satisfy one inequality but not the other.  Points that satisfy the other inequality but not the first.  Points that satisfy both inequalities  Points that satisfy neither of the inequalities The solution of a system of linear inequalities is the section of the plane where the points satisfy both inequalities.
