Equation of the circle of radius square root of 2 text  ´ containing the point  end text left parenthesis 31 right parenthesis text  and touching the line  end text vertical line x minus 1 vertical line equals vertical line y minus 1 vertical line is

  1. x to the power of 2 end exponent plus y to the power of 2 end exponent minus 4 x minus 2 y plus 3 equals 0    
  2. x to the power of 2 end exponent plus y to the power of 2 end exponent minus 6 x plus 4 y plus 11 equals 0    
  3. x to the power of 2 end exponent plus y to the power of 2 end exponent minus 6 x minus 2 y plus 8 equals 0    
  4. x to the power of 2 end exponent plus y to the power of 2 end exponent plus 4 x plus 4 y plus 6 equals 0    

The correct answer is: x to the power of 2 end exponent plus y to the power of 2 end exponent minus 6 x minus 2 y plus 8 equals 0
