Grade 9 • Album 2
Graphing & Linear Systems
Master the coordinate plane, slope, line forms, and systems — the backbone of algebra and real-world modeling.
Why it matters
- Coordinate plane → turn relationships into visuals.
- Slope → describe rate of change in real life.
- Line forms → switch between ways to represent the same line.
- Systems → find where two relationships intersect.
- Methods → graph, substitute, or eliminate depending on the problem.
