Vidushi Chadha Goel on Instagram: "✅How to find the perpendicular slope 1.Find the original slope This is given or can be calculated from an equation or two points. 2.Find the reciprocal: Invert the fraction to get the reciprocal. For example, the reciprocal of \(3/4\) is \(4/3\). 3.Change the sign: Make the new fraction negative if the original was positive, and positive if the original was negative. The result is your new slope. #teachersofinstagram #igcse #learning #grade10 #cbse"
