Question

△pqr is rotated 180° around the origin to form △pqr. what are the coordinates of point p and point p? p (\boxed{1}, ?) p (?, ?)

Explanation:

Step1: Find coordinates of P

From the graph, P is at (4, 1).

Step2: Apply 180° rotation rule

180° rotation: $(x,y)→(-x,-y)$. So P'( -4, -1).

Answer:

P (4, 1), P' (-4, -1)
