###
coordinate plane

A coordinate system formed by the intersection of a horizontal number line, called the x-axis, and a vertical number line, called the y-axis.

###
ordered pair

A pair of numbers, (x, y), that indicate the position of a point on a Cartesian plane.

###
term

a number, a variable, or the product of a number and a variable

###
variable

A letter or symbol used to represent a number.

###
sum

a quantity obtained by addition

###
difference

the number that remains after subtraction

###
quotient

the number obtained by division

###
product

a quantity obtained by multiplication

###
coefficient

number in front of a variable

###
constant

a quantity that does not vary

###
domain

the set of values of the independent variable for which a function is defined

###
range

###
combine like terms

add or subtract the coefficients of the variables

###
algebraic expression

A mathematical phrase involving at least one variable and sometimes numbers and operation symbols.

###
integer

The set of whole numbers and their opposites

###
function

an input-output relationship that has exactly one output for each input

###
operation

calculation by mathematical methods

###
expression

a group of symbols that make a mathematical statement

###
exponent

indicates the number of times a quantity is multiplied by itself

###
square number

the product of a number and itself

###
slope

the steepness of a line on a graph, equal to its vertical change divided by its horizontal change

###
y-intercept

where the line crosses the y axis

###
monomial

an expression with only one term

###
polynomial

a mathematical expression that is the sum of a number of terms

###
linear equation

a polynomial equation of the first degree

###
Intercept

the point at which a line intersects a coordinate axis

###
Intersecting lines

Lines that cross

###
Minimum

the smallest possible quantity

###
Maximum

the largest possible quantity

###
Constant Difference

the difference that is always the same from one term to the next number

###
Negative Exponent

an exponent less than zero which causes the base and its exponent to move positions in a fraction

###
Slope

the steepness of a line on a graph, equal to its vertical change divided by its horizontal change

###
Quadratic Function

a function that can be written in the form f(x)=ax^2+bx+c, where a, b & c are real numbers and a is not equal to zero

###
Exponential Function

a function in which an independent variable appears as an exponent

###
Square Root Function
