Graph the piecewise function given by

f(x)= -1/3x +2, x<0
x-5,x>0

1. if you can graph one line, surely you can graph two.

You can see the two lines at

http://www.wolframalpha.com/input/?i=plot+y+%3D+-1%2F3+x+%2B+2%2C+y%3Dx-5+for+x+%3D+-5+to+10

Just pick the blue line left of x=0 and the purple line to the right.
