The … 56 0 obj <> endobj %PDF-1.5 %���� Double inequalities:5 < 7 < 9 read as 7 less than 9 and greater than 5 is an example of double inequality. The concept is conceptually developed based on the truth value of the inequality and then the standard graphing algorithm is developed and practiced. Then combine the solutions at the end. Example:10 > 8, 5 < 7 Literal inequalities:x < 2, y > 5, z < 10 are the examples for literal inequalities. And the graph of linear inequality is the graph for all solutions/ordered pairs in the system. Solve word problems that involve linear inequalities in two variables. Find an equation of the line passing through the two points. The inequality is expressed in slope-intercept form in level 1 and has to be converted to slope-intercept form in Level 2. Some lessons, such as graphing linear inequalities, do involve the modeling method in introducing a new concept such as a dotted line for the boundary line. ���x���� w�y��Q�kjk$ 0��p�0���u��ѻ,�G�a=V�`��3@��u�$��?w��w�Y�n�����zQ�B�����u�e5��s��(Ή��,C3F���ƅ��0Lj�_Ѹj=�E�,��S�ȯ��̕����EM᳓���¦h�Zz����Z~������ȁ��\������R���2�^�ɘ�3t4�%F��X��Ђ 1) y x x y This website uses cookies to ensure you get the best experience.
