Step-by-Step Solution
Distance from the -axis equals the magnitude of the -coordinate, which is |7| = 7 units.
Answer: D) 7
What is the perpendicular distance of the point (−3, 7) from the -axis?

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.
