 * 1 ||  || Open GeoGebra. Use the **View** menu to display the coordinate axes. ||
 * 2 ||  || Type y = - x + 4 to construct a line passing through //A// and //B//. ||
 * 3 ||  || Type f(x) = 0.5x^2 - 4.5x + 9 to construct a parabola passing through points //A// and //B//. ||
 * 4 ||  || To construct the intersection, type A = (2,2) and B = (5,-1) in the input bar and press the ENTER key after each equation. ||
 * 5 || [[image:text.png]] || We label the graphs. To label the graph of the quadratic function, click the **Insert Text** tool, and click on the Graphics view near the graph of the quadratic function to display the //Text dialog box//. ||
 * 6 ||  || In the text dialog box, type f(x) = 0.5x^2 - 4.5x + 9 in the //Edit// text box, then click the //Latex formula// check box to check it, and then click the **OK** button. Notice what happens to the text. ||
 * 7 ||  || Now, label the graph of the linear function and the coordinates of A and B with (2,2) and (5,-1) respectively. ||
