Write the coordinates of the orthocentre of the triangle formed by the lines xy=0 and x+y=1.
Lines of triangle are xy=0 and x+y=1
∴x=0,y=0,x+y=1
In this case,
Point of intersection of altitudes from
vertices if O(0,0)
Orthocentre=(0,0)
Write the coordinates of the orthocentre of the triangle formed by the lines x2−y2=0 and x+6y=18.
