1. Teacher Orientation Linear Equations in two Variables Introduction Conditions with two lines in a plane Methods to solve LEs

2. Student Orientation  Linear Equations in two Variables  Introduction  Conditions with two lines in a plane  Methods to solve LEs

3. Concept  An equation which involves only two variables with highest power 1 is called an LE in two variables  Pair of LEs  The two lines will intersect at one point  The two lines will be parallel  The two lines will be coincident  Methods to solve LEs  Graphically  Elimination  Substitution  Cross multiplication  Application of LEs in day to day life
