READThis 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 inequalitiesThe solution of a system of linear inequalities is the section of the plane where the points satisfy both inequalities.
