No of new lines formed by intersection points of All non parallel lines

If the area (in sq. units) of the triangle formed by the intersection of a line parallel to the x - axis and passing through the point P(h, k) with the line y=x and x+y=2 is 4h^(2) , then the locus of the point P is

The area of the triangle formed by the intersection of a line parallel to x-axis and passing through P(h,k) with the lines y=x and x+y=2 is 4h^(2). Find the locus of the point P.
