TRANSCRIPT
Start-Up Day 4Write 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.
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
Let’s Graph a Few with a Graphing Calculator & use what we see to make general conclusions about the graphs of Absolute Value Functions.
Conclusions!
