Example 3 from Algebra and Trigonometry, 2.1 The Rectangular Coordinate Systems and Graphs

Using a Graphing Utility to Graph an Equation

Use a graphing utility to graph the equation: $y = - \frac{2}{3} x + \frac{4}{3} .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
Enter the equation in the y= function of the calculator. Set the window settings so that both the x- and y- intercepts are showing in the window. See Figure 10.
