We use it to find:
1- y-intercept
2- The point (x,y) , if you are given x you can find y and vice-versa.
3- Solve Linear Equations.
Finding y-intercept and point (x,y)
Steps :
1- Ctrl – N ( If it asks to if you want to save click No )
2- Add Graph:2. Enter
3- del 6: Relation ( Remember f(x)=y )
4- Write down the relation the way it is. Enter
5- Menu 5 ( Trace ) 1 ( Trace Graph ) Enter → This always take you to y-intercept (0,y-intercept)
6- Esc
7- Hover with mouse and move the y-intercept point to an empty space in the screen. and you will get the point (x,y).
8- Double click where you want to change the x or the y as asked in the question.
Solving Linear Equations
Steps :
1- Ctrl – N ( If it asks to if you want to save click No )
