Linear Function

 

Definition:

A linear function is a polynomial of degree one.  The graph of a linear function is a straight line.  The rate of change of a linear function is called the slope of the function.  In a linear function, the average and instantaneous rate of change are always the same.  

 

Formula for a Linear Function:

General Form: Ax + By + C = 0

 

Slope-Intercept Form: y = mx + b

 

Point-Slope Form: (y - y1) = m(x - x1)

 

Two-Point Form:  Formula

Mr. Lee's Example Photo

 

 

 

Photo Description: This is a picture of the Chapel Bridge in Lucern, Switzerland that I took while on vacation.  The roof of this footbridge, originally constructed in 1333, can be modeled by a linear function.  I set the origin at the base of the stone tower.  Given this somewhat arbitrary origin, the roof of the bridge could be modeled by the function y = 0.25x + 2.
