Distance Between Ordered Pairs

Front

What is the distance formula for two points (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 locate a point on a coordinate plane, written as (x, y).

Front

How do you find the distance between two points with the same x-coordinate?

Back

Subtract the y-coordinates and take the absolute value.

Front

What is the distance between the ordered pairs (5,-2) and (5,8)?

Back

10 units.

Front

What is the distance between the ordered pairs (0,5) and (0,-5)?

Back

10 units.

Front

Identify the ordered pair that represents point x: (5,-3), (-3,5), (3,-1), (1,-3).

Back

(1,-3).

Front

Identify the ordered pair that represents point y: (5,-3), (-3,5), (1,-2), (1,-3).

Back

(5,-3).

Front

What does the x-coordinate represent in an ordered pair?

Back

The x-coordinate represents the horizontal position on the coordinate plane.

Front

What does the y-coordinate represent in an ordered pair?

Back

The y-coordinate represents the vertical position on the coordinate plane.

Front

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

Back

Use the absolute difference of the y-coordinates.
