The vocab on Collazo's test on 2/16.

Two variable equation

An equation in which the value of one variable is dependent upon the other variable


The x coordinate of an ordered pair


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,


The measure of the steepness of a line

Standard form


Point Slope Form



a set of ordered pairs


the set of first (x) coordinates of a relation


The set of second (y) coordinates of a relation


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)


The horizontal number line in the coordinate plane


The vertical number lone in the coordinate plane


The four sections the x,y axes divided the coordinate plane into
