In an ordered pair, which number is the x-coordinate?

Explanation:
An ordered pair shows a location by two numbers written as (x, y). The x-coordinate is the first number, and it tells how far to the right (positive) or left (negative) the point is on the horizontal axis. The second number is the y-coordinate, which tells how far up (positive) or down (negative) the point is on the vertical axis. For example, in (4, -2) the x-coordinate is 4 and the y-coordinate is -2. So the x-coordinate corresponds to the first number in the pair.
