hi ramesh,

given eqs:y=x,y=2x,y=3x-2

by using each set of euations u can find apexs of triangle:A(0,0);B(1,1);C(2,4)

after knowing three points find circum centre by all perpendicular bisectors.

Next by using circum centre(a,b) and calculated radius r(by measuring form centre to any on apex)

find eq of circum circle by eq:(x-a)^2+(y-b)^2=r^2

thanks
