4-1 The Coordinate Plane
Numbers are graphed on a number line. Ordered pairs of numbers
are graphed on a coordinate plane. A coordinate plane has two
perpendicular number lines that divide it into 4 quadrants. The
following chart will help you identify the quadrants and the
coordinates of points on a coordinate plane.

To find the coordinates of P, start at
(0, 0). Move 3 units
, then 2 units .
So the coordinates of P are (3, 2),
and P is in quadrant IV.
To plot point Q with coordinates (1, 2),
start at (0, 0). Move 1 unit
, then 2
units . Q is in quadrant II.
y
Identify the quadrant and the coordinates of
each point on the coordinate plane at the right.
