## PERSONAL INFORMATION:

**Name:** Jeff Jackson

**Certification:** 8-12

**Major or:** Mathematics

Areas of emphasis

UNIT INFORMATION:

DESIGN ELEMENTS FOR UNIT:

Name of Unit: Linear Functions

**Grade: **10^{th}

**Subject:** Advanced Algebra

## 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 .

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.
