Gateway Algebra (2/9/2010) Find Solutions to systems of two linear equations in two variables

Gateway Algebra: 0806.3.1 Solving systems of linear equations

Solve systems of equations graphically.

Steps:

1. Solve each equation for "Y" if they are not already in Slope/Intercept Form
2. Enter each equation into TI Nspire calculator.
3. Window-Zoom and drag until intersection of both lines is visible.
4. Use Trace Graph to locate coordinate of the point of intersection. Where the lines cross is the solution to the system.
