1. Start-Up Day 4 Write your equations in Point-Slope Form. 1.Determine the equation of a line which passes through (1,-1) & is parallel to line: 2x +3 y = 8 2.Determine the equation of another line which passes through the same point, but is perpendicular to the line: 2x + 3y = 8.

2. Day 3 Linear and Absolute Value Functions and Inequalities

3. Objective - Students will be able to graph absolute value and linear equations and inequalities in two variables. Essential Questions: What are the differences between solving linear equations in two variables and solving linear inequalities in two variables? Home Learning: P. 118-119 #16, 20, 21, 22, 25, 30, 53, 54

4. Section 2-7 p. 1-7 Absolute Value Functions

6. Let’s Graph a Few with a Graphing Calculator & use what we see to make general conclusions about the graphs of Absolute Value Functions.
