- A(2, −3)
- B(3, 2)
- C(−3, 2)
- D(−3, −2)
Step-by-Step Solution
P is units to the left of the -axis, so , and units above the -axis, so . Hence P is .
Answer: C) (−3, 2)
Point P is plotted on the Cartesian plane (each grid square is 1 unit). What are the coordinates of P?

Key idea: Reading coordinates
Given a point on a graph:
1. Drop a perpendicular to the -axis. Where it hits is the -coordinate.
2. Drop a perpendicular to the -axis. Where it hits is the -coordinate.
3. Combine: .
Reverse if you're given coordinates: read first (horizontal direction), then (vertical direction). Don't swap their roles.
