alleryStart learning →A point written as an ordered pair has its two numbers in an order that:
AMatters to location
BCan be swapped
CIs always identical
DHas no meaning
Answer & Solution
Correct answer: A. Matters to location
1. The word ordered is doing work in the name.
2. In the rectangular coordinate system every point is represented by an ordered pair.
3. The first number is measured along one axis and the second along the other.
4. Swapping them would name a different point.
5. So the order matters to the location.
