Course 1

6-6 Ordered Pairs

Cities, towns, and neighborhoods are often laid out on a grid. This makes it easier to map and find locations.

A coordinate grid is formed by horizontal and vertical lines and is used to locate points.

Each point on a coordinate grid can be located by using an ordered pair of numbers, such as (4, 6). The starting point is (0, 0).

• The first number tells how far to move horizontally from (0, 0).

• The second number tells how far to move vertically.
