The door’s distance from the left wall is its x-coordinate, which is 9 units. Its distance from the x-axis is its y-coordinate, which is 0 units as it lies on the horizontal axis.
If D1 R1 represents the door to Reiaan’s room, how far is the door from the left wall (the y-axis) of the room? How far is the door from the x-axis?

In a coordinate system, the x-coordinate represents the perpendicular distance of a point from the y-axis (the left wall). For the door D1 R1, the x-coordinate of D1 is 9, meaning it is 9 units away from the left wall. The y-coordinate represents the distance from the x-axis. Since the door lies directly on the x-axis, its y-coordinate is 0, meaning the door is zero units away from the x-axis.
