Question

What is the orthocenter of the triangle with two altitudes given by the lines x = -1 and y = x + 1?

Answer 1

Please, remember the definition of orthocenter of a triangle.

Answer 2

According to Google: The three altitudes intersect in a single point, called the orthocenter of the triangle. The orthocenter lies inside the triangle if and only if the triangle is acute

Answer 3

Ok! now you have two lines, at whici point, those lines intersect each other?

Answer 4

-1, 0? I'm not really good at Geometry. :(

Answer 5

Ok!, now there is a theorem, which states that the third altitude must pass at that point.
