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 is the distance between the ordered pairs (9,2) and (9,-7)?

Back

9 units.

Front

What is the distance between the ordered pairs (-2,12) and (7,12)?

Back

9 units.

Front

What is the distance between the ordered pairs (10,12) and (10,5)?

Back

7 units.

Front

How do you identify the x-coordinate in an ordered pair (x, y)?

Back

The x-coordinate is the first number in the ordered pair.

Front

How do you identify the y-coordinate in an ordered pair (x, y)?

Back

The y-coordinate is the second number in the ordered pair.

Front

What does it mean for two points to have the same x-coordinate?

Back

It means the points are vertically aligned on the Cartesian plane.

Front

What does it mean for two points to have the same y-coordinate?

Back

It means the points are horizontally aligned on the Cartesian plane.

Front

If two points have the same x-coordinate, how do you calculate the distance between them?

Back

Use the formula: d = |y2 - y1|.

If two points have the same y-coordinate, how do you calculate the distance between them?

Back

Use the formula: d = |x2 - x1|.
