The Coordinate Plane

GPS A GPS, or global positioning system, is a satellite-based

navigation system. A GPS map of Tallahassee, Florida, is shown.

1. Suppose Mr. Diaz starts at Carter Howell Strong Park and drives
   2 blocks east. Name the street he will cross.


2. Using the words north, south, east, and west, write directions to go
   from Old City Cemetery to Carter Howell Strong Park.

A coordinate plane is formed when two number lines intersect.

The number lines separate the coordinate plane into four regions

called quadrants.

(^5) The y-axis is the
vertical number
line.
The origin is the point of
intersection of the two
number lines.
The x-axis is the horizontal
number line.
An ordered pair is a pair of numbers, such as (3, -2), used to locate a
point in the coordinate plane.
Main Idea
Graph points on a
coordinate plane.
