Answer:
O = (3,3)
Explanation:
The <em>altitude</em> of a triangle is the perpendicular from a vertex to the opposite side.
The orthocentre (O) of a triangle is the point where the three vertices intersect.
We must find the equations for only two of the altitudes, because the third will also intersect at that point.
===============
Your three points make a right triangle.
The altitude of B is side AC.
The altitude of C is sde AB.
Their point of intersection at A (3,3) is the orthocentre of thetriangle.
