A3 1.1 EQUATIONS AND INEQUALITIES

Rectangular coordinate system: Cartesian Coordinate SystemPoints: Quadrants: Signs:

Graphing in this system:1. by table of values2. using your grapher3. graphing the characteristics of the equations (e.g. x-intercepts, y-intercepts,opening up, opening down, translations, stretch or shrink factors… )

x

y

Examples of graphs:

No x-intercept 1 x-intercept

No intercepts 1 x-int, 3 y-intercepts

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

Your Grapher:

Viewing windows on your grapher:

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