Domain
another name for the possible values of x

Graph
set of all points in a coordinate plane that represent all the solutions of the equation

intercept
when and equation is solved in the form y = mx + b, b represents the yintercept

Range
in a function, the possible values for Y



System
two or more linear equations with the same variables

Variable
a quantity that changes or the can have different values

Alternate Exterior Angle
These angle are on opposite sides of the transversal and are outside the other two lines

Alternate Interior Angles
These angles are on opposite sides of the transversal and are in between the other two lines

Complementay Angles
two angles whose sum is 90 degrees

Congruent
having the same size, shape, and measure

Corresponding Angles
angles that have the same relative positions in geometric figures

Equiangular
the property of a poly gon whose angles are all congruent

Equalateral
the poroperty of a polygon whose sides are all congruent

Parallel Lines
two lines that lie in the same plane and do not intersect

Perpendicular Lines
two lines that intersect at a right angle

Supplementary Angles
two angles whose sum is 180 degrees

Transversal
a line that crosses two ro more lines

Vertical Angles
two nonadjacent angles formed by intersecting lines or segments

Associative Prop of Addition
changing the grouping of the numbers in a sum does not change the sum
Ex: (9+6)+2 = 9+(6+2)

Associative Prop of Mult
changeing the grouping of the numbers in a product does not change the product
Ex: (3x10)x4 = 3x(10x4)

Commutative Prop of Add
in a sum, you can add the numbers in any order

Commutative Prop of Mult
in a product, you can multiply the numbers in any order
Ex: 8(5) = 5(8)

Distributive
a(b+c) = ab + ac

Addition Prop of Equality
adding the same number to each side of an equation produces an equivalent equation

Multiplication Prop of Equality
multiplying both sides of an equation by the same number produces an equivalent expression
