SYSTEMS OF EQUATIONS Solving Graphically (Page 8 of 8)

Repeat this process to find the other x-intercept. We will use a left bound of 0.5, a right bound of 1.5, and a guess of 1. Then return to the Home screen to compute the y-coordinate.

 2nd CALC key. 2: menu selection. 0.5 ENTER key. 1.5 ENTER key. 1 ENTER key.
