Vocabulary
Slide2absolute value
The distance of a number from zero on a number line.
Slide3coordinate graph
A system of graphing ordered pairs of numbers on a coordinate plane.
Slide4decimal
The point between
the whole number in the ONES PLACE and the number in the TENTHS place in a decimal number.
Slide5equivalent fractions and ratios
Two fractions
or ratios __:__
that have the
same
numerical value.
Slide6fraction
A number expressed in the form
where
a and b are integers and b is not equal to 0.
Slide7integers
Whole numbers (not fractions) that can be positive, negative or zero.
Slide8least common multiple
The smallest common
multiple
of a set of two or more integers.
Slide9lowest terms/ simplest form
A fraction for which the numerator and the denominator have no common factor greater than one.
Slide10multiplicative identity
If any number or expression is multiplied by the number 1, the result is equal to the original number or expression.
Slide11opposite
The same number but with the opposite sign (+ or −). The additive inverse.
Slide12o
rdered pairs
Two numbers written in order as follows: (x, y). The first coordinate (x) represents the horizontal distance from the origin. The second coordinate (y) represents the vertical distance from the origin.
Slide13origin
The point on a coordinate plane where the x-axis and y-axis intersect. This point has coordinates (0, 0). Also
,
the
point assigned to zero on a number line.
Slide14percent
A ratio that compares a number to 100.
Slide15point
An exact location in space. In a coordinate plane, an ordered pair shows its location.
Slide16portion
A part of something; a part of a whole.
Slide17prime factors
A factor that is a prime number.
Slide18quadrants
The coordinate plane is divided into four of these.
Slide19ratio
Compares two quantities by division. Usually represented as a fraction.
Slide20sample
A subset (group) of a given population with the same characteristics as the whole population.
Slide21scale drawing
A drawing that shows a real object with accurate sizes except they have all been reduced or enlarged by a certain amount (called the scale factor).
Slide22simplify
To write a less complicated expression with the same value.
Slide23x-axis
The horizontal number line on a coordinate grid.
Slide24x-coordinate
In an ordered pair, (x, y), it is the value of the x.
Slide25y-axis
The vertical number line on a coordinate grid.
Slide26y-coordinate
In an ordered pair, (x, y), it is the value of the y.
