Firstly, we need to draw graph
we can see that
this is right angled triangle
and we know that
Orthocenter is the point of intersection of the altitudes
and Each leg in a right triangle forms an altitude
So, in a right-angled triangle, the orthocenter lies at the vertex containing the right angle
Hence, point B will be orthocenter
so,
Orthocenter is (4,0)........Answer
