###
Abscissa

The x coordinate of an ordered pair

###
Ordinate

The y coordinate of the ordered pair

###
Linear Equation

An equation that can be put in standard form (Ax+By=C) and A, B, and C are integers,

###
Slope

The measure of the steepness of a line

###
Point Slope Form

y-y₁=m(x-x₁)

###
Relation

a set of ordered pairs

###
Domain

the set of first (x) coordinates of a relation

###
Range

The set of second (y) coordinates of a relation

###
Function

A relation in which different ordered pairs have different first (x) coordinates

###
Direct Variation

an equation in the form of y=kx and where k is a non-zero constant

###
Inverse Variation

y=k/x or xy=k and x is not equal to 0

###
k (in terms of direct variation)

- called constant of variation

- called constant of proportionality

###
k (in terms of inverse variation)

called constant of variation

###
Slope Formula

m = (y2 - y1) / (x2 - x1)

###
x-axis

###
y-axis
