Slope

m, rise/run, constant rate of change, difference of ycoordinates divided by the difference of the xcoordinates


y = mx + b

SlopeIntercept Form


Ax + By = C

Standard Form


the m in y = mx + b

the slope


the b in y = mx + b

the yintercept


y  y1 = m(x  x1)
(y minus ysub 1 = m(x minus xsub1) 
Point Slope Form


Slope of a Vertical Line

Undefined


Slope of a Horizontal Line

Zero


Equation for a vertical line

x = xintercept
such as x=5 is the vertical line through the point (5,0) 

Equation for a horizontal line

y = b
such as y=3 is the horizontal line through the yintercept of 3 which is the point (0,3) 

Relation

a set of ordered pairs
such as {(3, 4), (2, 1), (5, 8)} 

Function

a relation (set of ordered pairs) where the xcoordinate produces only one ycoordinate (x's don't repeat!)
{(3, 4), (2, 1), (5, 8)} function {(3, 4), (2, 1), (3, 5)} is not a function because the xcoordinate of 3 produced two ycoordinates. 

Domain

the input value, the xcoordinate


Range

the output value, the ycoordinate
