I have tried going through the TI-84 plus manual that came with my calculator, so that I can graph this linear equation: 3x+4y=-16. I have not been able to graph linear equations. Can someone please tell me how to enter this equation properly into my calculator? I have solved the problem manually.
Thank you
its -2,9 hope it helps!
Sure, I'd be happy to help you with graphing the linear equation on your TI-84 Plus calculator!
To enter the equation into your calculator, follow these steps:
1. Press the "Y=" key on your calculator to enter the function menu.
2. You will see a list of functions on the screen. Use the arrow keys to scroll to the first empty function line.
3. Enter the equation into the function line. For the equation 3x + 4y = -16, you need to enter it as "3x + 4y = -16". To enter the variable 'x', use the "X,T,θ,n" button above the multiplication sign. To enter the variable 'y', use the "ALPHA" button followed by the "TRACE" button, which represents the letter 'Y'.
4. After entering the equation, press the "ENTER" key to confirm.
Now that you have entered the equation into your calculator, you can try graphing it by following these steps:
1. Press the "GRAPH" button located at the top right of your calculator. This will display the graph of the equation.
2. You may need to adjust the window settings to ensure that the graph is properly displayed. Press the "WINDOW" button to adjust the x-axis, y-axis, and scale settings according to your preference. You can set the x-min, x-max, y-min, and y-max values to determine the range of the graph.
3. Once you have set the window settings, press the "GRAPH" button again to display the updated graph.
If you have followed these steps correctly, you should now have the graph of the linear equation 3x + 4y = -16 displayed on your TI-84 Plus calculator.
I hope this helps! Let me know if you have any further questions.
