# LINEAR FUNCTIONS

## PERSONAL INFORMATION:

Name: Jeff Jackson
Certification: 8-12
Major or: Mathematics
Areas of emphasis

## DESIGN ELEMENTS FOR UNIT:

Name of Unit: Linear Functions

## CONTENT: Major Topics covered in unit:

A. Constant-Increase or Constant-Decrease Situations
B. The Graph of y = mx + b
C. The Graph of Ax + By = C
D. Finding the Equation of a Line
E. Point- Slope Formula
F. Parallel and Perpendicular Lines

## UNIT OVERVIEW:

The first few days of this unit the students will be learning situations where there are constant
changes . They will next learn how to graph y = mx + b and Ax + By = C linear functions using slope
and y- intercept . Once they learn how to graph the functions, they will learn how to determine the
equations of a line given two points . They will end the unit by learning how to determine the
relationship of parallel and perpendicular linear equations .

## TARGETED STANDARDS:

No. Text of Standard

logic of various mathematical systems

Core Content:
No. Content Information

MA-H-2.1.4 Students will describe properties of , define, give examples of, and apply to both realworld
and mathematical situations ratio measures including slope and rate .

MA-H-2.1.2 Students will define, describe properties of, give examples of, and apply to both realworld
and mathematical situations spatial relationships such as betweenness,
parallelism, and perpendicularity.

MA-H-4.2.2 Students will graph the equation of a line.

## DESCRIPTION OF PERFORMANCE EVENT:

Students create a letter of the alphabet using only linear equations (excluding some of the more
round letters, AEFHIKLMNTVWXYZ) by graphing this letter and providing the equations of each of
the lines used to form the letter.
