perpendicular number lines


the horizontal number line


the vertical number line

coordinate plane

the plane containing the x- and y-axes

ordered pair

points in the coordinate plane, named (x, y)


the first number of an ordered pair, corresponds to a number on the x-axis


the second number of an ordered pair, corresponds to a number on the y-axis


the point where the axes intersect, coordinates (0,0)

graph ordered pair

plot the point on the coordinate plane that corresponds to the ordered pair


the halfway point of a segment between two ordered pairs, (add x coordinates/2, add y coordinates/2)


a set of ordered pairs, can be represented by ordered pairs, a table, a graph or a mapping


illustrates how each element of the domain is paired with an element in the range


the set of x values of a relation


the set of y values of a relation

inverse of any relation

switch the coordinates in each ordered pairs

equation in two variables

y = 3x - 4 is an example because it contains two variables, x and y

solution of an equation in two variables

an ordered pair of replacements for the variables that results in a true statement when substituted into the equation

independent variable

the domain values of a relation

dependent variable

the range values of a relation


a relationship between input and output values, there is exactly one output (range) value for each input (domain) value

coordinate system

where you can represent the graph of a function

linear equation

an equation that can be written in the form Ax + By = C

standard form of a linear equation

Ax + By = C, where A ≥ 0, A and B are not both zero, and A, B, and C are integers whose GCF is 1


the point where the graph of a line intersects the x-axis, has y-coordinate of 0


the point where the graph of a line intersects the y-axis, has x-coordinate of 0

function notation

ƒ(x), x represents elements of the domain, and ƒ(x) represents the elements of the range, "ƒ of x"


a set of numbers in a specific order

arithmetic sequence

a numerical pattern that increases or decreases at a constant rate

common difference

the rate at which an arithmetic sequence increases or decreases

nth term of an arithmetic sequence

first term + (n - 1)d
