100
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
