First plot the lines and calculate the intersection points of the given lines.
the given eqns are:
 
y = x
y = -x
and
y =1
 
Let say points of intersection be:
(x1,y1)  (x2,y2)  and (x3,y3)
 
the incentre will be:
((ax1 + bx2 +cx3)/(a+b+c)  ,(ay1 + by2 +cy3)/(a+b+c)) 
 
where a,b and c are the dstances between the coordinates of the tringles opposite to vertices of triangle ABC.
