 y-intercept and point (x,y)

Solving linear equations

Mixed Problems

 

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.
