Answer:
The relationship between the number of tiles (x) and the length of the hallway covered (y) can be expressed using the equation y = 5x. This is derived from the given information that 10 tiles cover the first 2 feet of the hallway. Therefore, for every 2 feet (or 10 tiles), the length covered (y) is equal to 2 feet, or 10 tiles, which can be represented as y = 5x, where x is the number of tiles and y is the length covered in feet
