 The lines 3x – 4y  =0 and x+y=0 intersect each other at    (0,0). 
Also the line 3x + 2y = 0 passes through (0,0) and is perpendicular to the third line 2x – 3y=7 . 
Therefore it passes through ORTHOCENTRE as it is perpendicular to third line and passes through the point of intersection of first and second line.
