naming ordered pairs

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 in the form (x, y).

Front

What does the first number in an ordered pair represent?

Back

The first number in an ordered pair represents the x-coordinate, which indicates the horizontal position on the coordinate plane.

Front

What does the second number in an ordered pair represent?

Back

The second number in an ordered pair represents the y-coordinate, which indicates the vertical position on the coordinate plane.

Front

How do you identify a point on a coordinate plane?

Back

To identify a point on a coordinate plane, use its ordered pair (x, y) where x is the horizontal distance from the origin and y is the vertical distance.

Front

What is the coordinate of the origin in a coordinate plane?

Back

The coordinate of the origin is (0, 0).

Front

If a point has coordinates (3, 5), where is it located?

Back

The point (3, 5) is located 3 units to the right and 5 units up from the origin.

Front

What is the significance of negative coordinates?

Back

Negative coordinates indicate positions to the left of the origin (for x) or below the origin (for y) on the coordinate plane.

Front

How do you plot the point (2, -3) on a coordinate plane?

Back

To plot (2, -3), move 2 units to the right and 3 units down from the origin.

Front

What is the distance between the points (1, 2) and (1, -2)?

Back

The distance is 4 units, calculated as the difference in the y-coordinates: |2 - (-2)| = 4.

Front

What is the relationship between ordered pairs and functions?

Back

In functions, each input (x-coordinate) is associated with exactly one output (y-coordinate), forming ordered pairs.
