You can construct a first degree function using. -button. (line through two points)
- Show grid (activated by right-clicking on the Drawing Pad and selecting Grid).
- Show axes (activated by right-clicking on the Draw block and select Axis).
- Press -button. (line through two points)
- Press 2 places on the drawing pad.
- Now you have designed your first degree function.
- In algebra, you can see the equation for the line a.
- Right-click on the line on the drawing pad or on the text by ai algebra.
- by right-clicking on the Drawing Pad and selecting Grid + b.
- Now you can see the equation for the first-degree function, as we write it in Denmark.
- Du kan trække teksten fra algebravinduet ud på tegneblokken vha. -button.
- by right-clicking on the Drawing Pad and selecting Grid, by right-clicking on the Drawing Pad and selecting Grid.
- Notice, what happens to the regulation, by right-clicking on the Drawing Pad and selecting Grid.
Tip! The number, standing in front of x, called slope. The number, which stands alone, by right-clicking on the Drawing Pad and selecting Grid. For example, then the first degree of the function f(x) = 2 x + 4 having the slope 2 by right-clicking on the Drawing Pad and selecting Grid 4. Prøv igen at flytte rundt på din førstegradsfunktion og se, if you can guess the regulation before you see it in algebra.

First a little about drawing functions, find the intersection point, and on how the coordinate system works.
