Calculus 1 — 1.1: Slope Formula and Point-Slope Form

Ever wondered how to find a line's equation from just two points? Here's the elegant secret: the point-slope form you memorize is actually the slope formula in disguise. This video reveals the direct connection and walks you through a complete example. Key concepts covered: • Slope as rise over run: m = (y₂ - y₁)/(x₂ - x₁) • How point-slope form y - y₁ = m(x - x₁) derives directly from the slope formula • Why two points are all you need to determine a unique line • Step-by-step method: calculate slope → apply point-slope form → convert to slope-intercept form • Why using either point gives you the same final equation ━━━━━━━━━━━━━━━━━━━━━━━━ SOURCE MATERIALS The source materials for this video are from    • Calculus 1 Lecture 0.1:  Lines, Angle of I...
