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.


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


A letter or symbol used to represent a number.


a quantity obtained by addition


the number that remains after subtraction


the number obtained by division


a quantity obtained by multiplication


number in front of a variable


a quantity that does not vary


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


The y-coordinates of the set of points on a graph. Also, the y-coordinates of a given set of ordered pairs. The range is the output in a function or a relation.

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.


The set of whole numbers and their opposites


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


calculation by mathematical methods


a group of symbols that make a mathematical statement


indicates the number of times a quantity is multiplied by itself

square number

the product of a number and itself


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


where the line crosses the y axis


an expression with only one term


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

linear equation

a polynomial equation of the first degree


the point at which a line intersects a coordinate axis

Intersecting lines

Lines that cross


the smallest possible quantity


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


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
