How do you identify a point on a coordinate plane?

Back

You identify a point by its ordered pair (x, y), where x is the distance from the origin along the x-axis and y is the distance along the y-axis.

What is the significance of the order in an ordered pair?

Back

The order is significant because (x, y) is different from (y, x); the first number always represents the x-coordinate.
