Question
a point located at $(-4,4)$ is rotated $180^{circ}$ about the origin. which of the following shows the coordinates of the points new location?
a) $(4,-4)$
b) $(-9,4)$
c) $(-3,4)$
d) $(4,4)$
Step1: Aplicar la regla de rotación 180°
La regla para rotar un punto \((x,y)\) 180° alrededor del origen es \((x,y)\to(-x,-y)\).
Para el punto \((-4,4)\), se aplica la regla:
\(x = - 4\), \(y = 4\)
Nuevas coordenadas: \((-(-4),-4)\)
Step2: Simplificar
\(-(-4)=4\)
Así, las coordenadas son \((4,-4)\)
