Question

  1. which of the following would rotate a point in the coordinate grid by ( 90^{circ} ) clockwise about the origin? (1) ( (x,y)\to(y,x) ) (3) ( (x,y)\to(-x,-y) ) (2) ( (x,y)\to(-y,x) ) (4) ( (x,y)\to(y,-x) )

Explanation:

Step1: Recuerda la regla de rotación

La regla para rotar un punto \((x,y)\) \(90^{\circ}\) en sentido de las agujas del reloj alrededor del origen es \((x,y)\to(y, -x)\).

Answer:

(4) \((x,y)\to(y, -x)\)
