1. HOMEWORK: P. 102-103 1-27 ODD, 41-46 ALL,55 A3 1.1 EQUATIONS AND INEQUALITIES

2. Rectangular coordinate system: Cartesian Coordinate System Points: Quadrants: Signs: Graphing in this system: 1. by table of values 2. using your grapher 3. graphing the characteristics of the equations (e.g. x- intercepts, y-intercepts, opening up, opening down, translations, stretch or shrink factors… ) x y

3. Examples of graphs: No x-intercept1 x-intercept No intercepts1 x-int, 3 y-intercepts

4. Line Graphs: often used to illustrate trends over time, with the x-axis representing the independent variable (usually time) and the y-axis representing the dependent variable. Example 6: Book

5. Your Grapher: Viewing windows on your grapher: X-values start at -2, end at 3, and change in increments of.5 Y-values start at -10, end at 20, and change in increments of 5 Tables in your grapher – reflect individual data points
