Chapter Three
Vocabulary
The set of whole numbers and their opposites;
including 0
Examples: -2, -7, 0, 10, 3
Two numbers are opposites if they are the same distance
from 0 on the number line but on different sides of 0.
+3 and -3 are opposites; zero is its own opposite.
Opposites
Any number that can be written as
Rational
Number
𝑎
𝑏
Where a and b are integers and b ≠0
Decimals, fractions, and integers are rational numbers.
Absolute
Value
The distance from 0 on a number line (how many
jumps from zero; direction does not matter).
The absolute value of -3 and +3 are both 3

Coordinate
Plane
x-axis, yaxis, origin,
quadrants
Coordinate Plane formed by a horizontal
number line called the x-axis that
intersects a vertical number line called
the y-axis. The axes intersect at 0 on
both number lines and that point where
they intersect is called the origin. The
four sections of the plane are separated
by
Ordered
Pair
Ordered pair is a pair of numbers, such
as (3, 5) that can be used to locate a
x-coordinate, point on the coordinate plane. The first
y-coordinate number is the x-coordinate; it tells the
distance to move from left or right from
the origin. The second number is the ycoordinate; it tells the distance to move
up or down from the origin. The ordered
pair for the origin is (0, 0).
(x, y)
(3, 5)
Line
Symmetry
A figure has line symmetry if it can be
folded about a line so that its two parts
match exactly.
Line of
Symmetry
A line that divides a figure into two
halves that are reflections of each
other.
