1. Day 5: Graphing Linear Inequalities Goal: To graph linear inequalities using tables or equations. AND To write equations to describe lines. Standard: 9.2.4.4 – Represent relationships in various contexts using systems of linear inequalities; solve them graphically. Indicate which parts of the boundary are included in and excluded from the solution set using solid and dotted lines. Guiding Question: How do I graph a linear inequality? AND How can I write equations of lines? Materials: Pencil, Folder, Student Packet 1Day 5: Graphing Linear Inequalities
