quadrilateral pqrs is rotated 90° clockwise about the origin to form quadrilateral pqrs. what is the y - coordinate of point p?
Answer
Explanation:
Step1: Recall rotation rule
The rule for a 90 - degree clockwise rotation about the origin is $(x,y)\to(y, - x)$.
Step2: Identify coordinates of P
From the graph, point $P$ has coordinates $(1,2)$.
Step3: Apply rotation rule
Using the rule $(x,y)\to(y, - x)$ for $P(1,2)$, we get $P'(2,-1)$.
