Coordinate Plane 

A vertical and a horizontal number line that intersect. 

100

X-Axis

The horizontal Axis on the coordinate plane. 

100

Y-Axis

The vertical axis on the coordinate plane.

100

Quadrants

The four regions of the coordinate plane. 

100

Origin 

The point of intersection between the X-Axis and the Y-Axis. Also known as (0,0)

200

Ordered Pair

The set of numbers, or coordinates written in the form (x,y) 

200

X-Coordinate 

The X-value of an ordered pair. (Represents the horizontal placement of the point)

200

Y- Coordinate 

The Y-value of an ordered pair. (The vertical placement of the point) 

200

Relation 

A set of ordered pairs. {(2,3),(4,-3),(5,6)}

200

Domain 

The set of X-Values in a relation

300

Range

The set of Y-Values in a relation

300

Function 

A relation where the each element of the domain only has one single unique range. (X's Don't repeat). 

300

Independent Variable 

The X value in a function. 

300

Dependent Variable 

The Y-Value in a function. 

300

Vertical Line Test

If any vertical line passes through a point of a line only once is a function. If any vertical line passes through more than one point is not a function. 

400

Rate of Change

A ratio that shows how one variable changes with respect to another. 

400

Slope

The change of Y over the Change of X.  Also known as M = RISE/RUN. 

400

Positive Slope
