Original Prompt

Create a comprehensive lesson on inequalities covering BOTH one-variable inequalities AND two-variable inequalities. Structure it with clear sections: introduction to one-variable inequalities with examples and practice, then transition to two-variable inequalities with graphing techniques and practice problems. Include worked examples, vocabulary, and practice problems for each section. The following is a summary of a document named 63e065fa-d0a9-4608-81c7-8bd0224e13f7%2Fuser_uploads%2FoyGzWHZ...

This resource introduces the concept of inequalities, focusing on how to graph and solve both linear and quadratic inequalities in one and two variables. It begins with definitions of key vocabulary such as 'less than' and 'greater than', followed by a review of number lines. The learning path includes two main steps: mastering one-variable inequalities and then progressing to two-variable inequalities. Step-by-step examples demonstrate the process of solving and graphing these inequalities. Special attention is given to the rules for isolating variables and the important note about flipping inequality signs when multiplying or dividing by a negative number. The document also introduces quadratic inequalities, showcasing methods for finding critical points and testing intervals, along with graphical representation. Guided practice and self-check exercises reinforce understanding, providing opportunities for students to apply their skills.
