Ti-84 graphing help

Is there a way to get my TI-84 to not draw the whole line in a graph? For example, if I want to graph a piece work function like f(×) = x+1 for x<2 and x-7 for x>2 can I get it to draw that to easily visualize it, or do I just have to have it draw both full graphs? It would be so much easier for me to see if I could get it to cut off where it needs to.
