VOCABULARY DEFINITION EXAMPLE
A coordinate plane is
formed by two number
lines in a plane that
COORDINATE
PLANE intersect at right angles.
The point of intersection
is zero on each number
line.
AXES The two number lines.
X-AXIS The horizontal axis.
Y-AXIS The vertical axis.
The two axes divide the
coordinate plane into
four quadrants or
QUADRANTS sections. They are
numbered with Roman
Numerals
counterclockwise.

2. ORIGIN
The point where the two
axes intersect. (0,0)
The ordered pair give the
location of a point on a
ORDERED PAIR coordinate plane. They (2,4)
are always written in
parenthesis.
COORDINATES
The numbers in the
ordered pair.
The first number in an
ordered pair that tells
X-COORDINATE how far to move right
(positive) or left
(negative).
The second number in an
ordered pair that tells
Y-COORDINATE how far to move up
(positive) or down (2,4)
(negative).
