The equation of the circle passing through ((0,0) ) and which makes intercepts (a ) and (b ) on the coordinate axes is
Options
- A(x^2+y^2+a x+b y=0 )
- B(x^2+y^2+a x-b y=0 )
- C(x^2+y^2-a x+b y=0 )
- D(x^2+y^2-a x-b x=0 )
Correct answer
D. (x^2+y^2-a x-b x=0 )
Step-by-step solution
( aligned & Centre = ( a 2 , b 2 ) & Radius = a^2+b^2 2 aligned ) Equation of circle ( aligned & (x- a 2 )^2+ (y- b 2 )^2= a^2+b^2 4 & x^2+a^2-a x+y^2+b^2-b x=a^2+b^2 & x^2+y^2-a x-b x=0 aligned )
