Question

Circumcenter of triangle formed by line xy+2x+2y+4=0 and x+y+2=0

Answer 1

The given equations are xy + 2x + 2y + 4 = 0 and x + y + 2 = 0.

By equating and rewriting a first given equation we can find the value of x= -2 and y=-2

Now, we can form and plot three lines on the given graph,

X= -2 ,  y=-2 , x+y+2=0

Now, we can see that the given triangle is a right triangle.

Hence, the circumcentre  of the triangle is the midpoint of the hypotenuse.

Thai is (-1, -1).
