Summary
• In this tutorial, you’ll explore the graphs of Linear Functions. The steps in the tutorial include:
– Creating a Graph Window.
– Graphing functions of these forms:
y =mx
y =mx + b

Create a Graph Window
Click on the + tool to activate this menu.

Input the Function
By default the keyboard is active.

Input the Function
Input the function shown. Press Enter.
f1(x) = x

Graph the Function
This is the basic graph of a Linear Function. Its slope is 1 and its y-intercept is 0.

Edit the Function
Click on the + sign at the upper right to bring up the Function Entry line. Then press the up arrow. You’ll see
f1(x).
Click here.
Then Click here.

Edit the Function
Change the function to the one shown above. Then press Enter. The orientation of the graph changes.
f1(x) = -x

Edit the Function
Now change the function to the one shown above. Press Enter. A greater slope value leads to a steeper
graph.
f1(x) = 2x
![Page 10: Nspire--iPadAppTutorial--Graphs of Linear Functions](https://reader033.fdocuments.in/reader033/viewer/2022060205/55a153c21a28abc42c8b4718/html5/thumbnails/10.jpg)
Edit the Function
Now change the function to the one shown above. Press Enter. A lesser value for slope leads to a less steep
line.
f1(x) =1
2x
![Page 11: Nspire--iPadAppTutorial--Graphs of Linear Functions](https://reader033.fdocuments.in/reader033/viewer/2022060205/55a153c21a28abc42c8b4718/html5/thumbnails/11.jpg)
Edit the Function
Now change the function to the one shown above. Press Enter. Note how the y-intercept displaces the
graph vertically.
f1(x) = x +1
![Page 12: Nspire--iPadAppTutorial--Graphs of Linear Functions](https://reader033.fdocuments.in/reader033/viewer/2022060205/55a153c21a28abc42c8b4718/html5/thumbnails/12.jpg)
Edit the Function
Now change the function to the one shown above. Press Enter. Note how the y-intercept displaces the graph
vertically.
f1(x) = x -1
![Page 13: Nspire--iPadAppTutorial--Graphs of Linear Functions](https://reader033.fdocuments.in/reader033/viewer/2022060205/55a153c21a28abc42c8b4718/html5/thumbnails/13.jpg)
Edit the Function
Now change the function to the one shown above. Press Enter. Note how the values for m and b affect the
graph of the function.
f1(x) = -3x +1
