Ordered Pairs and Coordinate Grid

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate grid, written in the form (x, y).

Front

What does the first number in an ordered pair represent?

Back

The first number represents the x-coordinate, which indicates the horizontal position on the coordinate grid.

Front

What does the second number in an ordered pair represent?

Back

The second number represents the y-coordinate, which indicates the vertical position on the coordinate grid.

Front

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

How do you identify a point on a coordinate grid?

Back

To identify a point, 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 origin in a coordinate grid?

Back

The origin is the point (0, 0) where the x-axis and y-axis intersect.

Front

If a point is located at (3, 4), what are its coordinates?

Back

The coordinates are 3 on the x-axis and 4 on the y-axis.

Front

What is the y-coordinate in the ordered pair (4, 9)?

Back

The y-coordinate is 9.

Front

What is the x-coordinate in the ordered pair (2, 5)?

Back

The x-coordinate is 2.

Front

How do you plot the point (5, 3) on a coordinate grid?

Back

Start at the origin (0, 0), move 5 units to the right (x-axis), and then move 3 units up (y-axis).
