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

How do you identify the coordinates of a point on a grid?

Back

To identify the coordinates of a point on a grid, locate the point's position in relation to the horizontal (x-axis) and vertical (y-axis) lines. The x-coordinate is determined by how far along the horizontal axis the point is, and the y-coordinate is determined by how far up or down the vertical axis the point is.

What does the ordered pair (5,5) represent on a grid?

Back

The ordered pair (5,5) represents the point located 5 units to the right of the origin (0,0) and 5 units up on the grid.

Front

If point A is located at (4,4), what does this indicate about its position on the grid?

Back

Point A is located 4 units to the right of the origin (0,0) and 4 units up on the grid.

Front

What is the significance of the first number in an ordered pair?

Back

The first number in an ordered pair represents the x-coordinate, indicating the horizontal position of the point on the grid.

Front

What is the significance of the second number in an ordered pair?

Back

The second number in an ordered pair represents the y-coordinate, indicating the vertical position of the point on the grid.

Front

How would you write the ordered pair for point X if it is located at (4,2)?

Back

The ordered pair for point X is written as (4,2), indicating it is 4 units to the right and 2 units up from the origin.

Front

What point does the ordered pair (0,2) correspond to on a grid?

Back

The ordered pair (0,2) corresponds to the point located at the origin (0,0) and 2 units up on the grid.

Front

How can you find the ordered pair for a given point on a grid?

Back

To find the ordered pair for a given point, measure the horizontal distance from the origin to the point (x-coordinate) and the vertical distance from the origin to the point (y-coordinate), then write it as (x, y).

Front

What does the ordered pair (1,5) indicate about point Z's position?

Back

The ordered pair (1,5) indicates that point Z is located 1 unit to the right of the origin and 5 units up on the grid.
