Algebra-2

2nd Semester

Overview

Algebra-2 Sequence• 4th Grading Period

– Chapter 3: Linear Systems of Equations and Inequalities– Chapter 9: Conics

• 5th Grading Period– Chapter 6: Inverses and Square Root Function– Chapter 7: Exponentials and Logs

• 6th Grading Period– Chapter 7: Exponentials and Logs– Chapter 8: Rational Functions

2nd Semester• All material is Algebra-2, very little repeat from

Algebra-1• 6th 6-weeks is the hardest of the three six week

periods. Get off to a good start!!• Weekly Factoring Quizzes (random this semester)• More homework graded for accuracy this semester!

Tuesday: Objectives

• Review Factoring Methods– GCF– Difference of 2 Squares– Reverse FOIL– Swing and Divide

• Review Linear Equations: y = mx + b

Linear Equations

• Slope-Intercept Format

y mx b

Slope y-intercept

Re-arranging to get format

• Most equations will need to be re-arranged to get y = mx + b

• This is usually where the mistakes are made!

• Let’s review this concept!

Graphing• Once you have y = mx + b

• Plot the y-intercept (b) on the y-axis

• Use slope (m) to get more points

• Connect with ruler
