In an ordered pair, which number is the second coordinate?

In an ordered pair, which number is the second coordinate?

• A. Second number
• B. First number
• C. Ordered pair
• D. X-coordinate

Answer: (A)

An ordered pair is two numbers written in a specific order. The first number is the first coordinate, and the second number is the second coordinate. In Cartesian form we often write it as (x, y), where x is the horizontal position (the first coordinate) and y is the vertical position (the second coordinate). So the second coordinate is simply the second number in the pair (for example, in (3, 5), the second coordinate is 5).
