2-7 Solving Equations With Algebra Tiles powerpoint Learning Target I can write and solve a system of inequality word problems with two variables by graphing. What do you already know about this target? M1.1.C Solve problems that can be represented by a system of two linear equations or inequalities. M1.3.E Write and solve systems of two linear equations and inequalities in two variables. ©Evergreen Public Schools 2011

©Evergreen Public Schools 2011 Launch Use the graph the inequality y ≥ x + 5 to determine Is (2, 5) a solution? Is (-1, 5) a solution? Is (1, 8) a solution? How do you know? This is the same graph presented in the Inequality powerpoint. How do students interpret the AND…especially in light of the work with systems of linear equations. ©Evergreen Public Schools 2011
