Question

The point
of intersection of the pair of lines
represented by Xy - 2x+2y-4=0​

Answer 1

Step-by-step explanation:

ANSWER

Pair of lines we have,

xy+2x+2y+4=0

x(y+2)+2(y+2)=0

(y+2)(x+2)=0

∴ sides of the triangle are

x=−2

y=−2

x+y=−2

Coordinates of the triangles are

(0,−2), (−2,0) and (−2,−2)

Given triangle is the right-angled triangle, therefore the circumcentre of the triangle is the midpoint of the hypotenuse.

Mid-point of hypotenuse is (

−2+0

,

0−2

)=(−1,−1)
