Distance Between Ordered Pairs

Front

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

Back

The distance formula is: d = √((x2 - x1)² + (y2 - y1)²).

Front

What does it mean if two ordered pairs have the same x-coordinate?

Back

They lie on a vertical line, and the distance between them is the difference in their y-coordinates.

What does it mean if two ordered pairs have the same y-coordinate?

Back

They lie on a horizontal line, and the distance between them is the difference in their x-coordinates.

How do you determine the distance between two points on a vertical line?

Back

Subtract the y-coordinates of the points and take the absolute value.
