Answer:correct
Step-by-step explanation:
Orthocenter is the point of concurrence of the altitudes of the triangle.
This means Orthcenter is the point where the altitudes intersect.
Here one altitude is x = -1
The other altitude is y = x + 1
Substituting x = -1 in y = x + 1
We get
y = -1-1=0
Hence the point of intersection of the altitudes is (-1,0)
The orthocenter of the triangle whose altitudes are x = -1 & y = x+1 is (-1,0)
(-1,0) which is Option c) or the third option is the right answer.
