# Will not graph

I put in an equation in the Y= then hit the graph key, the x and y axis show up then dots start crossing the screen, then it says Err: 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.

Does that do any good?

Having gone over a month without a response, I assume turning off the stat plot features did the trick.

That is an equation describing a straight line. The "slope-intercept" form of a line is

y = mx + b

where m is the slope (change in y-value / change in x-value)
and b is the y-intercept (the point where the line crosses the y-axis when x=0)

Positive slope means the line is rising and negative slope means it's falling.

You can rewrite the original equation 2x - 4y -9 = 0 in slope-intercept form:

y = (1/2)x - (9/4)

So you know the slope is positive 1/2 (line rises 1 y-unit for each 2 x-unit change) and crosses the y-axis at -9/4. With this information you can graph the line.

### My TI-84 PLUS calculator wont show the graph after i type in an equation. please help!

You need to fix your graph so that it shows the correct y-axis and x-axis.
It works best if you press the zoom button and then scroll to find the ZoomFit option.
Then the graph should show up.

### Find the equation of the hyperbola which satisfies the given equation center(1,-2) transverse axis to the x-axis transverse 6 and conjugate axis 12

I am not quite sure how the major axis of your hyperbola is directed and i do not know if the lengths you give are measures of the major and minor axes or the measures of the semi-major and semi-minor axes. So I am giving you the equations and the graphs so that you can decide for yourself what is appropriate for your problem.

Major axis parallel to the X-axis
Equation and graph

Center is at x=1 and y=-2, semi-major axis length is a=6, and semi-minor axis length is b=12

Major axis is parallel to the y-axis
Equation

Center is at x=1 and y=-2, semi-major axis length is a=12, and semi-minor axis length is b=6.

I trust you can customize the equations to fit your need.

### Graph button won't graph, then it exits and put's a 4 instead ?

Hello,
It seems that wires got crossed. I suggest you reset all RAM by the follwing steps
[2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]
Ram cleared will be displayed on screen. [CLEAR] to go to the home screen.

If that does not solve your problem, reinstall the OS. Post a question on how to install OS, if you want, or read some of the posts on TI83/84/89 about same subject.

If nothing works, I am afraid you will have to repair the calculator.

Hope it helps.

### Err: no sign chng

When you get the sign change error it is either that you have mixed up the left bound and the right bound or that you are marking the left and the right bound both above the x-axis or both below the x-axis. That's why you get the sign change error. Your range values must have different signs.

### I put the equation into y= and then i hit graph. when i do, the screen comes up as ERR: INVALID DIM. help i need to graph!

dont you have to chose if its quadratic or not? I'mnot 100% sure if thats right my calculator isn't working so i cant check if thats what your doing wrong ir if thats for something else

### Solver not working properly

try a simple equation like x^2-1 which should come out with x = 1,-1

no sign change would indicate that the graph of the curve never crosses the x axis, if you graphed the above equation and calculated the zeros, it would come out with -1, 1 which it should, but if you put in x^2+1, the graph would never cross and therefore have no sign change from pos to neg or vice versa, the left-rt are the left and right bounds or the lower and upper bounds which was corrected in later calculators, Please let me know the outcome of graphing both of the above equations and then putting them in the solver. you could also use the quadratic equation to prove the answers if you liked, hope this helps
