Relatively Prime
When the greatest common factor of two numbers is 1
Rational Number
Any number that can be expressed as a ratio of two integers
Reciprocal
One of two numbers whose product is 1, also called multiplicative inverse
Relation
A set of ordered pairs
X Coordinate
The first number in an ordered pair; it tells the distance to move right or left from the origin (0,0)
Y Coordinate
The second number in an ordered pair; it tells the distance to move up or down from the origin (0,0)
X Axis
The horizontal axis on a coordinate plane
Y Axis
The vertical axis on a coordinate plane
Coordinate Plane
A plane formed by the intersection of a horizontal line (the x-axis) and a vertical line (the y-axis)
Vertical Line Test
A method for seeing if a graph represents a function; if the graph is ever intersected by the line more than once, it is not a function
Dependant Variable
The output of a function
Continuous Graph
A graph made up of connected lines or curves
Independent Variable
The input of a function
Discrete Graph
A graph made up of unconnected points
Quadrant
One of the four regions that the coordinate plane is divided into by the x-and y-axes
Range
The set of all possible output values for a function
Function
An input-output relationship that has exactly one output for each input
Domain
The set of all possible input values for a function
Ordered Pair
A pair of numbers that can be used to locate a point on the coordinate plane
Origin
The point where the x-axis and y-axis intersect on the coordinate plane
Hypotenuse
In a right triangle, the side opposite the right angle
Density Property
The property that states that between any two real numbers, there is always another real number
Exponent
For a product, a number that is multiplied by itself to form the product
Legs
In a right triangle, the sides that include the right angle
Pythagorean Theorem
In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs
Scientific Notation
A method of writing very large or very small numbers by using powers of 10
Irrational Number
A number that cannot be expressed as a ratio of two integers or as a repeating or terminating decimal
Real Number
A rational or irrational number
Perfect Square
A square of a whole number
Principal Square Root
The non-negative square root of a number
Rate
A ratio that compares two quantities measured in different units
Cross Product
The product of numbers diagonal from each other in a comparison of two ratios
Center of Dilation
The point of intersection of lines from all the angles in a dilation
Dilation
A transformation that enlarges or reduces a figure
Corresponding Sides
Matching sides of two or more polygons
Corresponding Angles
Angles in the same relative position in polygons with an equal number of sides
Unit Rate
A rate in which the second quantity in the comparison is one unit
Unit Price
A unit rate used to compare prices
Scale Factor
The ratio used to enlarge or reduce similar figures
Similar Figures
Figures with the same shape but not necessarily the same size
