Questions?
In past years we studied systems of linear equations. We learned three different methods to solve them. Elimination, Substitution and Graphing
To solve is to find the intersections of the graph. Put each in slope intercept form and graph
1. Type equation 1 = y 1, equation 2 = y 2 2. Push 2 nd TRACE 5, move cursor to the left intersection push ENTER 3 times. 3. Push 2 nd TRACE 5, move cursor to the right intersection push ENTER 3 times.
