Standard Form and Intercepts Guided Notes
A guided-notes packet for 9th graders that introduces the standard form of linear equations (Ax + By = C), states its rules, and walks through worked examples of finding x- and y-intercepts. It builds algebraic manipulation and graphing readiness, with step-by-step examples and practice problems designed for a single class period of direct instruction followed by independent work.

Teacher Guide & Tips
- Use this as the note-taking anchor for a 45 to 60 minute lesson: present the standard form rules, work Example 1 together, then have students complete the remaining practice items on their own or in pairs.
- Discussion question: Why do we set y = 0 to find the x-intercept, and what does that tell us geometrically about where the line crosses the axis?
- Scaffold for struggling readers: Have them copy each substitution step into a two-column table (what we set equal to zero, and the resulting equation) before solving, and check that A, B, and C are integers first.
- Extension for advanced students: Ask them to explain why A must be non-negative by rewriting an equation like -2x + 5y = 10 in standard form, and to determine which special cases (such as a zero coefficient) produce horizontal or vertical lines.
- Estimated time: about 15 minutes for the worked examples and 20 to 30 minutes for independent practice.
