Distance Between Ordered Pairs

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 in the form (x, y), where x is the horizontal coordinate and y is the vertical coordinate.

Front

How do you identify the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair (x, y) and represents the horizontal position on the coordinate plane.

Front

How do you identify the y-coordinate in an ordered pair?

Back

The y-coordinate is the second number in an ordered pair (x, y) and represents the vertical position on the coordinate plane.

Front

What is the distance formula for two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the distance between the ordered pairs (2, 3) and (2, 7)?

Back

The distance is 4 units.

Front

What is the distance between the ordered pairs (4, 5) and (1, 5)?

Back

The distance is 3 units.

Front

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

Back

If two points have the same x-coordinate, they lie on a vertical line.

Front

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

Back

If two points have the same y-coordinate, they lie on a horizontal line.

Front

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

Back

The distance is 10 units.

Front

What is the distance between the ordered pairs (1, 3) and (1, -3)?

Back

The distance is 6 units.
