Question

quadrilateral pqrs is rotated 90° clockwise about the origin to form quadrilateral pqrs. what is the y - coordinate of point p? type the answer in the box.

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 point P

From the graph, the coordinates of point $P$ are $(0,2)$.

Step3: Apply rotation rule

Using the rule $(x,y)\to(y, - x)$ with $x = 0$ and $y = 2$, we get $P'(2,0)$.
