Coordinate Graphing
Quadrants and Reading
Ordered Pairs
The
coordinate
plane is
formed by
the
intersection
of two
number
lines.
Origin, the
point where
the two
number lines
intersect
y-axis, it is
the vertical
number line
x-axis, it is
the
horizontal
number line
x
You can graph points on the
coordinate plane. A point has two
coordinates which form an ordered pair.
The x coordinate tells how far to
move left or right along the x-
axis.
The y coordinate tells how far to
move up or down along the y-axis.
(3, -4)
Example 1
What are
the
coordinates
of point A?
A
Start at the
origin. Move
2 units to
the right.
The x
coordinate is
2.
Move up
from the x
axis. The y
coordinate is
4.
The
coordinates
for point A
are (2, 4).
Example 2
What are
the
coordinates
of point B?
B
Move 5 units left
from the origin.
The x coordinate is
-5.
Move down
from the x
axis to point B.
The y
coordinate is -
2.
The
coordinates
for point B
are (-5, -2).
Practice
Write the
ordered pair
for each
point. A
B
C D
E
F
A (-7, 4)
B (3, -3)
C (3, 0)
D (7, 1)
E (0, -7)
F (-6, -4)
The coordinate plane is divided
into four quadrants.
Quadrant II Quadrant I
Quadrant IV

quadrant
is point C
located?

Closure
What are the signs for
all of the x-coordinates
and all of the y-
coordinates of the
ordered pairs in the
second quadrant? x negatives, y
positives
