How can a graphing calculator help you find the solution to a system of equations? Consider this system:
5x - y = 35
3x + y = -3
a. First graph the system in a standard window. Can you see the solution on your screen?
b. To find the solution you will need to change the window on your calculator. Discuss with your team what maximum value, minimum value, and scale
you should use for the 2- and y-axes in order to see the intersection. After you have decided, check your conclusion on the graphing calculator.
c. Use a "trace" function on your calculator to find the solution from the graphs. Then solve the system algebraically.
d. Discuss the two methods with your team. Explain which one your team prefers and why.
