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.

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.
