When I plug an equation into the y= and hit graph it says there is an invalid dim


You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

How to set a ti-84 to graph both sides of the equation separately on the same coordinate system.


If I'm understanding you correctly, you want to graph something like

5x+3=9

If this is correct, graph 5x+3 in the y1 line and 9 in the y2 line. To find the solution, you will press 2nd, then trace the intersection and hit enter 3 times. This will get the solution you need for the equation.

If this is not what you are wanting to do, you need to be try again and elaborate more.

I am entering information from a sample question for drawing a scatterplot and finding the linear regression equation. I have copied the example exactly and keep coming up with the same two problems. 1. I...


You might not see the scatter plot when you go to the graph because the boundaries are not set correctly. With the scatter plot turned on, go to "zoom" and then scroll down to "zoomStat" and hit enter. Try going to the graph again and see if the the scatter plot shows up. As for the the equation being slightly different than the examples, this is probably just the calculator rounding up the answers it gets. Good luck!

Ti 84 plus problem


The calculator only displays from -10 to 10 on the x and y axes, and both of your lines are outside of that range. However, it is easy to change that.

1. Hit the gray "WINDOW" button that is directly under the screen
2. Change "Xmax" to 150
3. Change "Ymax" to 200

Remember to change both of those values back to 10 when you are done with this problem!

Here's how to graph it:
1. Hit the "Y=" button
2. Enter your first equation after Y1, and your second equation after Y2
3. Look over both the equations to make sure you typed them correctly
4. Hit the "GRAPH" button
5. If you don't see the intersection you will need to adjust Xmax and Ymax again
6. Hit Hit "2ND" and the "TRACE" to bring up the "CALC" menu
7. Scroll down to "intersect" and hit enter
8. Hit enter 3 times (You use the first and second curve options when you have more than 2 lines)
9. It should display the coordinates at the bottom
10. I got (76, 142.1) for the intersection

Thanks for asking this question! I used to do this a much harder way, but while I was calculating the answer to your question I hit a wrong button and accidentally found this method!

How to graph 2 lines at once


ok well go to the 'y=' button
type in the equation and make sure that the equals sign after y has like a black box around it, making the actual = white. so make sure both of those = signs of the 2 equations that you want to graph are like that, and thats about it.
