How do you graph Y on a TI-84?
Step 1: Press Y= and enter the first equation. Arrow down and enter the second equation. Step 2: Press GRAPH and your will see the graphs of the two equations. Note: The graphs are shown in the standard viewing window.
How do you graph inequalities on a graph?
There are three steps:
- Rearrange the equation so “y” is on the left and everything else on the right.
- Plot the “y=” line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
- Shade above the line for a “greater than” (y> or y≥) or below the line for a “less than” (y< or y≤).
What are inequalities on a graph?
An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.
How do you graph inequalities on a ti 84 Plus?
Ti-84 Plus Graphing Calculator For Dummies, 2nd Edition Use the arrow keys to place the cursor on the sign of the function or inequality you are defining. Press [ALPHA] and press the key under the appropriate equality or inequality symbol. To get the first screen, press [ALPHA] [ZOOM] to enter a less-than or equal sign.
How to graph the inequality y < 2x-4?
Graph the line y = 2x − 4 as a dashed line. After you have plotted the line, shade in the area to right of the line. Remember to make it a dashed line to indicate that it is not included. Here is a how it should look:
How to create an inequality graph in Excel?
Press y/. Press ~ to select the INEQUALITY menu. Select 1: Point of Interest Trace. Since both Y 1 and Y 2 are strict inequalities, the notation used in the expression area is Y 1, Y 2, which is called a point of interest.
Where is the greater than sign on a ti 84 Plus?
Where is the greater than sign on a TI 84? That tells us that we can get to the “Test Menu” if we press [2nd] (the blue key) then the [test] buttom (Math). You will see this menu: TEST is already highlighted, so just press the  button to choose the “ greater than ” symbol .
