Parallel and Perpendicular Lines FAST 🚀 Learn in Minutes!

Learn parallel and perpendicular lines faster than ever. In just a few minutes, you’ll master how to write their equations, find slopes instantly, and never confuse them again. What you’ll learn in this video: 1. Parallel Lines – same slope, different intercept. Quickly find the slope and plug it into your new equation. 2. Perpendicular Lines – negative reciprocal slope. Flip it, change the sign, and you’re done. 3. All equation forms covered: • Slope formula → m = (y2 − y1) / (x2 − x1) • Point-slope form → y − y1 = m(x − x1) • Slope-intercept form → y = m x + b • Standard form → A x + B y = C 4. How to tell when two lines are parallel, perpendicular, or neither — instantly. By the end, you’ll be able to write any line equation on sight. No guessing, no memorizing — just fast logic. ⸻ 📺 Watch this next: ➡️ All You Need to Know About Lines 📏 This video connects perfectly with today’s topic — watch it next to understand every line formula in depth and strengthen your foundation. ⸻ HOMEWORK QUESTIONS Follow this order: Identify slope → Use correct formula → Simplify → Convert. 1. Write the equation of a line parallel to y = 3x − 4 passing through (6, 2). 2. Write the equation of a line perpendicular to y = 3x − 4 passing through (6, 2). 3. Determine whether each pair of lines is parallel, perpendicular, or neither: a) y = −2x + 5 and y = −2x − 1 b) y = ½x + 3 and y = −2x + 1 4. The line through (1, 3) and (5, 7): • Find its slope. • Write the equation of the line parallel to it passing through (1, −2). • Write the equation of the line perpendicular to it passing through (1, −2). 5. Bonus: Convert 2x + 5y = 10 into slope-intercept form and state its slope and intercept. ⸻ Call to Action: If this helped you learn faster than school ever did, subscribe and click the bell icon!
