Question

△pqr is rotated 180° around the origin to form △pqr. which coordinate is the same as the x - coordinate of point p? x - coordinate of point p y - coordinate of point p opposite of x - coordinate of point p opposite of y - coordinate of point p p(3,1) p(-3,-1)

Explanation:

Step1: Recall rotation rule

When rotating a point 180° around origin, $(x,y)$ becomes $(-x,-y)$.

Step2: Analyze x - coordinate

For point $P(x,y)$ and $P'(-x,-y)$, x - coordinate of $P'$ is opposite of x - coordinate of $P$.

Answer:

Opposite of $x$-coordinate of point $P$
