# How to Calculate Y Value on Ti 84

In mathematics, the y-value is the output of a function when the input is the x-value. In other words, it is the value of y that corresponds to a given value of x. The y-value can be found on a graph by finding the point where the line intersects with the y-axis.

It can also be calculated using an equation.
To calculate the y-value on a TI 84 calculator, first press “2nd” and then “VARS.” Next, press “F1” for “func.”

Then, enter the function you want to use. For example, if you want to find the y-value for x = 2 in the equation y = 3x + 5, you would enter 3x + 5 into your calculator. To find out what 2x + 5 equals, press “enter.”

Your answer should appear onscreen as 11.

- Turn on your TI-84 calculator
- Press the “Y=” button located on the top left of the keypad
- Enter in your equation using the appropriate symbols and numbers
- For example, if you wanted to calculate y=5x+3, you would type 5*X+3 into the calculator
- Press the “GRAPH” button located above the keypad to graph your equation
- Locate where your line intersects the y-axis by looking at the coordinate readout in the bottom left corner of the screen while moving along your line with either arrow keys or by tracing with your finger (if you have a touch screen TI-84)
- The number displayed next to “Y=” is your y value! In our example, it would be 3 since that’s where 5x+3 intersects the y-axis when x=0

## How Do You Find Y on a Graphing Calculator?

There are a few different ways that you can find the y-coordinate on a graphing calculator. One way is to simply type in the equation for the line or curve that you are trying to graph and then press the “evaluate” button. This will give you the y-coordinate for a specific x-coordinate that you can input.

Another way is to use the trace feature on most graphing calculators. To do this, you first need to graph the equation of interest and then press the “trace” button. This will allow you to move along the curve and see what the corresponding y-coordinate is for each x-coordinate.

## How Do You Find the Y Value of a Function?

To find the y value of a function, you need to plug in the x value into the equation and solve for y. For example, if you have the equation y = 2x + 1 and you want to find the y value when x = 3, you would plug 3 in for x and solve for y. This would give you y = 7.

## How to Find X Value Given Y on Ti-84 Plus

If you need to find the value of x given y on a Ti-84 Plus calculator, there are a few steps you’ll need to follow. First, press the “Y=” button. This will bring up a list of equations that you can scroll through.

Find the equation that matches the one you’re trying to solve, and press enter. Next, input the value of y into the equation by pressing the appropriate buttons. Once you’ve done this, press “2nd” followed by “x-1.”

Doing so will give you the value of x that you’re looking for.

In mathematics, the coordinate system is one of the most fundamental tools. It allows us to pinpoint the location of any point in space using only two numbers. The coordinate system is also a powerful tool for graphing equations.

In this blog post, we’ll show you how to use a coordinate system to find the y-value of any given x-value using a simple calculator.
To start, let’s review the basics of the coordinate system. The coordinate system is made up of two perpendicular lines, called axes, that intersect at a point called the origin.

The horizontal axis is called the x-axis and the vertical axis is called the y-axis. Each point in space can be uniquely identified by its x- and y-coordinates. For example, the coordinates of the point shown below are (3,2).

The coordinate system is also used to graph equations. To graph an equation, we plot points that satisfy the equation on a graph paper and then connect those points with a line or curve. For example, consider the equation y=2x+1.

We can plot points that satisfy this equation by finding values of x and then calculating corresponding values of y using the formula y=2x+1 . Below are some examples:
If x = 0 , then y = 2(0) + 1 = 1 .

So we plot (0,1) on our graph paper.
If x = 1 , then y = 2(1) + 1 = 3 . So we plot (1,3) on our graph paper as well…and so on!

Now that we’ve reviewed some basics about coordinates and graphing equations, let’s get back to our original question: How do we use a coordinate system to find the y – value of any given x – value? While there are many ways to do this mathematically, here we will show you how to use a simple online calculator tool to find these values quickly and easily!
First go to www.desmos.com/calculator . This website will allow us to input equations and calculate corresponding values quickly and easily!
Next click on “Input” located on left side bar near top of screen . A text box should appear where you can type in your equation For our purposes today ,we want to solve fory so our input will be in terms ofx .

## How to Find X Value on Ti-84 Plus Graph

Finding the x-value of a graph on a TI-84 Plus calculator can be done by using the trace feature. To use this feature, follow these steps:
1. Press the TRACE button on your calculator.

2. Use the arrow keys to move to the point on the graph that you want to find the x-value for.
3. Press ENTER. The x-value will be displayed on the screen.

## How to Find X Value from Y Value on Graphing Calculator

If you need to find the x-value of a point on a graph, there are a few different ways you can do it depending on what type of graphing calculator you have.
If you have a TI-84 Plus CE graphing calculator, you can use the built-in function called Trace. To access Trace, press 2nd then CALC and then select 4:Trace.

You’ll see the trace cursor appear on your screen. Use the arrow keys to move the cursor around until it’s on top of the point you want to find the x-value for. Once the cursor is in place, press Enter and then look at the value that appears next to X= at the bottom of your screen.

This is the x-value of your point!
If you have a TI-Nspire CX CAS graphing calculator, finding the x-value is a little bit different. First, make sure your graph is displayed in Function mode by pressing MODE and then selecting 1:FUNCTION.

Then, press F5 to access Evaluate and enter in the y-value of your point using either t he keypad or by writing it out on scratchpad . After you’ve entered in the y – value , press ENTER and then look at th e value that appears next t o X= at t he bottom of your s creen . Just like with t he TI – 84 Pl us CE , this i s t he x – value o f yo ur p oint !

## Conclusion

The Y value on a Ti 84 calculator can be found by inputting the X value into the Y= function and solving for Y. The user must first input the known X values into the calculator. Next, the user inputs the equation they are solving for into the Y= function. Finally, the user solves for Y by pressing 2nd then F1.
