Question

3.
The centres of the circles x² + y2 =1, x2 + y2 +6x - 2y = 1
and x2 + y2 - 12x + 4y =1 are
(a) Same
(b) Collinear
(c) Non-collinear
(d) None of these​

Answer 1

Answer:

d ) non- collinear

Step-by-step explanation:

x²+y²=1, x²+y²+6x-2y=2, x²+y²-12x+4y =1

because in the first no x and y teams
