 First: Get books at station 4  When return, create calculator log in › Type first name, last name, username (lastnamefirst initial, ex. EixenbergerR) › 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

 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!)

 Warm up: Given 4x+7y=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

 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

 Go over special slopes › Undefined › Zero › Parallel › Perpendicular  1.1, 1.4:  3.1:  3.3:

 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!

 Find the intersection of these 2 lines › Y=4x+7 › Y=-5x+3  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 lessons)

 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
