4. Learn to graph ordered pairs on a coordinate grid.

5. Vocabulary
coordinate grid
ordered pair

6. Cities, towns, and neighborhoods are often laid out on a grid
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.

7. Additional Example 1A: Identifying Ordered Pairs
Name the ordered pair for the location.
Gym
Start at (0, 0). Move right 2 units and then up 3 units.
The gym is located at (2, 3).

8. Additional Example 1B: Identifying Ordered Pairs
Name the ordered pair for the location.
Theater
Start at (0, 0). Move right 3 units and then up 1 unit.
The theater is located at (3, 1).

9. Additional Example 1C: Identifying Ordered Pairs
Name the ordered pair for the location.
Park
Start at (0, 0). Move right 4 units and then up 2 units.
The park is located at (4, 2).

10. Check It Out: Example 1A
Name the ordered pair for each location.
Diner
Start at (0, 0). Move right 10 units and then up 5 units.
The diner is located at (10, 5).

11. Check It Out: Example 1B
Name the ordered pair for each location.
Pool
Start at (0, 0). Move right 12 units and then up 1 units.
The pool is located at (12, 1).

12. Additional Example 2: Graphing Ordered Pairs
