Answer 2

Answer:

The othocenter of the triangle XYZ is (-3,3)

Step-by-step explanation:

The triangle itself is a Right-angled Triangle. A right-angled triangle  is a triangle in which one angle is a right angle (that is, a 90-degree angle). Therefore, the two sides of the triangle (except hypotenuse) is already an altitudes of the both sides. Altitude of the hypotenuse is also comes from the corner X. Therefore, three altitudes are meeting at one point X(-3,3) which is an othocenter.
