Class 11 Maths | Equation of a Line & All Forms Explained | Slope-Intercept, Two-Point, Point-Slope

Hello baccho, Welcome back to our Class 11 Straight Lines series! 📘 In this video, we learn one of the most important and frequently used concepts in the entire chapter — the **Different Forms of the Equation of a Straight Line**, along with simple examples and NCERT-based questions. These forms are the foundation for all future coordinate geometry topics, including distance from a line, angle between lines, intersection of lines, and more. --- 📘 *Forms of Line Equation Covered in This Lesson:* ✔️ Slope–Intercept Form → y = mx + c ✔️ Point–Slope Form → y – y₁ = m(x – x₁) ✔️ Two-Point Form → (y – y₁)/(y₂ – y₁) = (x – x₁)/(x₂ – x₁) ✔️ Intercept Form → x/a + y/b = 1 ✔️ Normal Form → x cos α + y sin α = p ✔️ General Form → ax + by + c = 0 ✔️ Conversion Between Forms --- 💡 *What You’ll Learn:* • How to choose the correct form based on the question • How to convert from one form to another • How slope and intercept determine the geometry of the line • How to write equations quickly in exams • How to solve simple NCERT problems using each form This is one of the MOST scoring parts of the chapter and forms the basis of JEE-level coordinate geometry. --- 📚 *Chapter Details:* Class: 11 Subject: Mathematics Chapter: 10 – Straight Lines Topic: Forms of Line Equation Board: CBSE | NCERT Level: Foundation | Concept Builder | JEE Preparation --- 🧩 *Coming Next:* ▶️ Distance of a Point from a Line ▶️ Family of Lines & Combined Equation of Pair of Lines --- 💬 *Try This Question:* Find the equation of the line passing through (2, –3) and slope = 4.
