How do you graph a diagonal line segment starting at zero on a graphing calculator?
This has nothing to do with school i just need to know how before Christmas. Thanks!

On a TI-84, you can use the " Truth" rules :
y1 =2x +3 , say, goes from -infinity to infinity
or from one side to the other if you are using a normal window.
It is true that you could just use a window with xmin = 0 and proceed.
a cuter trick :
If the segment starts from the y axis :
y1 = (2x+3 )(x > 0) use the regular x, and you will find the > symbol in the test menu, above math
if you want it to start from (0,0) then its going to be y = 2x + 0
so to limit the domain :
y1 = (2x)(x>0)
and you can even draw double ended segments with TWO truth statements :
y2 = (2x -1)(x>1)(x<4)
And finally ... Note that if you do a single ended ray, or a double ended segment, you will get vertical sticks at the starting and stopping points... not so pretty
This last trick comes from one of my students :
Instead of multiplying by the two truth statements : Try dividing by them :
y3 = (2x -1) /( (x>1)(x<4))
and Voila ..a segment with no end hassles...Source(s): Retired Math Teacher

You enter function of the form f(X)=Xm+c mit c=0. the you set the window to only show the the areas you want, which in your case would be Xmin=0, Xmax>Xmin, Ymin=0, Ymax>Ymin.

yes origin is at +300, this means when you first started your measurement the value was 300.

Define the function F(x)=mx+b, x>0, where m and b are both real.
