Question
what is the new x - coordinate when the following point is rotated 90° about the origin in a counterclockwise direction? (10,8)
Step1: Aplicar la fórmula de rotación de \(90^{\circ}\) en sentido antihorario
La fórmula para rotar un punto \((x,y)\) \(90^{\circ}\) en sentido antihorario alrededor del origen es \((x,y)\to(-y,x)\)
Step2: Sustituir los valores de \(x = 10\) y \(y = 8\)
Sustituyendo \(x = 10\) y \(y = 8\) en la fórmula \((x,y)\to(-y,x)\), obtenemos \((10,8)\to(-8,10)\)
