Look at your answers to Questions 1 and 2. Does the horizontal distance between two points on the same horizontal line depend on the x-coordinate or the y-coordinate?
The horizontal distance between two points on the same horizontal line depends on the x-coordinate.
The horizontal distance between two points on the same horizontal line depends on the x-coordinate. This is because the x-coordinate represents the position of a point along the horizontal axis, while the y-coordinate represents the position of a point along the vertical axis.
