To be pefectly honest, your question really doesn't make sense. 160 is a rational number, and there isn't any irrational number that's related, connected, or tied to it in any particular way.
The graph y=|x|-4 is obtained from the graph y=|x| dy <span>moving down 4 units the graph y=|x| along the y-axis (see, if x=0, then for y=|x|, y=0 and for y=|x|-4, y=-4). </span> These two graphs have the same form. <span />
