# CK-12 Texas Instruments Algebra I Student Edition

**At Grade**Created by: CK-12

- 1.
## Introduction

A brief overview of what is covered in the following chapters.

- 2.
## Equations and Functions

This chapter defines functions and ordered pairs using examples on a graphing calculator, including the MACHINE program.

- 3.
## Real Numbers

This chapter goes through the process of using a factor tree to find composite numbers. Additionally, the HOTAIR program is used to illustrate integer addition and subtraction.

- 4.
## Equations of Lines

This chapter shows students how to input equations into a graphing calculator, including one step equations and, utilizing the App4Math application, equations with variables on both sides. Additionally a brief overview of percentages is given.

- 5.
## Graphs of Equations and Functions

This chapter uses the Cabri Jr. and TRAINS applications to explore the concepts of points, lines, and slopes.

- 6.
## Writing Linear Equations

This chapter again uses the Cabri Jr. application in order to describe the properties of perpendicular slopes. Also covered is an introduction to using a graphing calculator to display real world data.

- 7.
## Graphing Linear Inequalities

This chapter describes methods of utilizing the LINEQUA and Inequalz applications to graph and solve inequalities with and without absolute values.

- 8.
## Solving Systems of Equations and Inequalities

This chapter uses the Transform and Cabri Jr. applications to solve systems of equations and inequalities. Students will learn to find how many solutions a system has, create a new system, and graph a given system.

- 9.
## Exponential Functions

This chapter uses the ExpRules program to explore six different rules of exponents. Also covered are a few examples of graphing and finding exponential growth on a graphing calculator.

- 10.
## Factoring Polynomials

This chapter covers the use of the AREA program in finding the area of polynomials and the Cabri Jr. application to explore more complex examples of factoring.

- 11.
## Quadratic Equations and Quadratic Functions

This chapter uses the Transformation Graphing application to explore the concepts surrounding quadratic equations. Also introduced is the QUAD program, which is used to solve quadratic equations with the quadratic formula.

- 12.
## Algebra and Geometry Connection; Working with Data

This chapter explores the graphing of square root functions through the Transfrm program, defines the distance and midpoint formulas, and goes over utilizing a box and whisker plot on a graphing calculator.

- 13.
## Rational Equations and Functions; Topics in Statistics

This chapter uses the graphing calculator to better describe the concepts surrounding inverse variation and the addition and subtraction of rational expressions.
