There are ways of achieving this analytically, but the simplest method is to generate a few sample data pairs:

$(x, y) :$ $(x,y):$
$(- 1, \pm 4)$ $(-1,+-4)$
$(0, \pm 3)$ $(0,+-3)$
$(1, \pm 2)$ $(1,+-2)$
$(2 \pm 1)$ $(2+-1)$
( $3, 0)$ $3,0)$

I will assume by "vertex" you mean the point where the two lines cross; $(3, 0)$ $(3,0)$
