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
