For the next two problems use a graphing calculator, if one is available, to graph the systems of equations. Otherwise, graph the system of equations on graph paper. |
|
|

Instructions for using a graphing calculator: In the [Y=] editor, set Y1 = to the first equation and Y2 = to the second equation. Press [GRAPH] and then [TRACE]. Use the right and left arrows to trace along the line of one of the graphs until the cursor lands on the point of intersection. The x-value and the y-value will be displayed at the bottom of the screen. |
