Question

How can you solve a system of equations using a graphing calculator?

Answer 1

To solve a system of equations using a graphing calculator, you can use two different methods: graphing and using a TI-83, 83+, or 84 calculator. Solution A involves graphing both equations and finding the intersection point. Solution B involves using the intersect function on the calculator.

Step-by-step explanation:

To solve a system of equations using a graphing calculator, you can use two different methods. Solution A involves graphing both equations and finding the intersection point. Solution B involves using the intersect function on a TI-83, 83+, or 84 calculator. Here is how you can use both methods:

Solution A: Graphing

1. Enter both equations into your graphing calculator by selecting the Y= button.
2. Graph both equations on the same coordinate plane.
3. Locate the point where the two graphs intersect. This point represents the solution to the system of equations.
4. Read the x and y coordinates of the intersection point to find the solution.

Solution B: TI-83, 83+, or 84 Calculator

1. Select the Y= button and enter both equations.
2. Press 2nd, TRACE, and select the intersect function.
3. Follow the prompts to find the intersection point, which represents the solution to the system of equations.
