Please Help !!!!!!

Hi Zac,

your answer looks great.  Did you use GeoGebra?

Thanks

Is that a program?

No I just used paint 

You can see where I used the eraser to make the dotted line 

oh okay

What about the LaTex.  Where did that come from?  Although I suppose only one line of it is specifically in Latex.

Yes GeoGebra is the program that I use for these sorts of pics.  It is a free download and it can do a lot of things.  It is not intuitive when you first start but you'll get the hang of it pretty soon.  You can use LaTex with it too.  I still learn new things with it all the time.

You should download it and have a play.    

Yeah I just typed it in.

I might just do that
