Answer:
p = 3
q = 4
Step-by-step explanation:
Rotation by +90° (clockwise) about the origin: (x, y) → (y, -x)
Therefore, (p, 4) rotated by +90° about the origin:
(p, 4) → (4, -p)
Therefore:
(4, -p) = (q, -3)
⇒ p = 3
⇒ q = 4
Therefore, (3, 4) is mapped into (4, -3) under a rotation by +90° about the origin.
