=Stage 1 Identify Desired Results= Equations and Inequalities Grades 9-Diploma 2 students will solve families of equations and inequalities** a. solve systems of linear equations and inequalities in two unknowns and interpret their graphs. ||
 * **Establish Goals:** **(G)** ||
 * **Maine Learning Results: Mathematics-D.Algebra

//What understandings are desired?//
•linear equations and inequalities can be solved by interpreting their graph. •linear equations and inequalities are used in everyday life. ||
 * //Students will understand that:// **(U)** ||
 * •linear equations are different than inequalities.

//What essential questions will be considered?//
•Why are graphs used to solve linear equations and inequalities? •How are linear equations and inequalities related to in the real world? ||
 * **Essential Questions:** **(Q)** ||
 * •How are there differences between linear equations and inequalites?

//What key knowledge and skills will students acquire as a result of this unit?//
•Formula- standard and slope intercept formulas. •Terminology- b as the y-intercept and m is slope. || •show key difference between linear equations and inequalities. •a. solve systems of linear equations and inequalities. •analzye graphs of linear equations and inequalities. •make sense of labeling and defining linear equations and inequalities. •recognize linear equations and inequalities are a part of everyday life. •relate linear equations and inequalities to the real world. ||
