9/5: Prep Day � First: Get books at station 4 � When return, create calculator log in › Type first name, last name, username (lastnamefirst initial, ex. Eixenberger. R) › Do not type a password yet › Pick up calculator, log in, set password on first log in � Class Procedures and Meet your teachers � Homework: Skills Review

1. 1, 1. 4: Recursive Sequences � Notation for Recursion � Recursion, Example A pg. 30 � Practice the notation together Ex B. pg. 32 � Investigation pg. 54 Match it up: graphs i, ii, v only (extension try to match the others!)

3. 1: Arithmetic and Linear � Warm up: Given 4 x+7 y=42, solve for y. What is the slope? Where is the y-int? � Review Arithmetic Sequence � Pg. 124 Ex. A: Arithmetic Sequence to Linear Function (class) � Pg. 126 Investigation: Match Point (group) � Pg. 126 Ex B: Story problem practice

3. 3: Slope and Fitting a Line � Warm up: Find the slope of a line � Pg. 139 Point Slope Form � Pg. 138 Finding a Line of Fit � Pg. 141 Investigation: The Wave

3. 1 -3. 3 Review � Go › › over special slopes Undefined Zero Parallel Perpendicular � 1. 1, � 3. 1: � 3. 3: 1. 4:

3. 6: Linear Models and Intersections � Warm UP: Find the equation containing the points (5, 8) and (8, 2) � Calculator Practice: Graphing Lines � Definition: Solving Systems � Example A pg. 161: Linear System with Story Problem � Example B pg. 163 � Note from quiz: let’s talk about y-hat!

3. 7: Solving a Linear System Algebraically � Find the intersection › Y=4 x+7 › Y=-5 x+3 of these 2 lines � Solving algebraically › Substitution (use example above) › Substitution (Example A pg. 167) › Elimination (Example B pg. 168) � Look over quizzes, but return before leaving (next quiz is next Tuesday, 9/18 over 3. 6 -3. 7 lessons)

3. 6 and 3. 7 Review � � Warm up Extra Definitions to check from Geo: › One Solution › No Solutions › Infinitely many Solutions � � Quiz tomorrow 3. 6, 3. 7 3. 6 › Linear Models-Intersections by calc › Writing Systems of Equations �Y-int and slope �Point of intersection, you write the system (infinite right answers) �Story problem � 3. 7 › Substitution to solve system › Elimination to solve system
