Linear Growth, Decay aur Patterns | Class 9 Chapter 2

Ek student roz ₹50 bachata hai — linear growth. Phone ki battery roz 15% drain hoti hai — linear decay. Dono alag lagti hain — lekin dono ek hi polynomial se describe hoti hain. ✅ Linear growth — positive slope, real examples ✅ Linear decay — negative slope, real examples ✅ Pattern identification — table se constant difference ✅ Graph interpretation — slope ka sign story batata hai ⏱️ Timestamps: 0:00 - Intro 0:20 - Linear growth 4:17 - Linear decay 8:15 - Pattern identification from table 11:27 - Graph reading 13:31 - Outro 📌 Chapter 2 Complete!
