Distance Between Ordered Pairs

Front

What is the distance formula for finding the distance between two ordered pairs (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, written as (x, y).

How do you find the distance between two points that have the same y-coordinate?

Back

Subtract the x-coordinates and take the absolute value.

Front

If the ordered pairs are (x, y) and (x, y + d), what is the distance?

Back

The distance is d.

Front

If the ordered pairs are (x1, y1) and (x2, y2), what does it mean if x1 = x2?

Back

The points are vertically aligned, and the distance is the difference in their y-coordinates.
