welcome

The three altitudes intersect in a single point, called the orthocenter of the triangle
|dw:1356884192910:dw|

This question is asking "where do the 2 lines intersect?"
x= -1    equation says x is always -1, no matter what y is
y = x + 1  is the other equation.  replace x with -1, and y = -1+1= 0
they intersect at (-1,0)
that is the orthocenter of a triangle that has those two lines as altitudes.
