Question 447701
it’s a circle, and the given equation is of the form

{{{x^2+y^2+2gx+2fy+c=0}}}


where ({{{-g}}},{{{-f}}}) is the {{{center}}}


{{{g=1}}} and {{{f=1}}}, so the center is at (-1,-1)


intercept on {{{x -axis=(g^2-c)^(1/2)}}}


substituting the values {{{x- intercept=0}}}


so, it {{{touches}}} {{{x}}} axis


intercept on {{{y- axis=(f^2-c)^(1/2)}}}


substituting the values {{{y- intercept=0}}}


so, it {{{touches}}} {{{y}}} axis
