What is the equation,in general form,of the circle whose center is (3,-2)and which contains the point (-1,-2)?
\n" ); document.write( "***
\n" ); document.write( "Standard form of equation for a circle: (x-h)^2+(y-k)^2=r^2, (h.k)=coordinates of center, r=radius
\n" ); document.write( "For given problem:
\n" ); document.write( "(x-h)^2+(y-k)^2=r^2
\n" ); document.write( "solve for r^2:
\n" ); document.write( "plug in coordinates of center
\n" ); document.write( "(x-3)^2+(y+2)^2=r^2
\n" ); document.write( "plug in coordinates(-1, -2) of given point on the circle
\n" ); document.write( "(-1-3)^2+(-2+2)^2=r^2
\n" ); document.write( "16=r^2
\n" ); document.write( "r=4
\n" ); document.write( "equation: (x-3)^2+(y+2)^2=4 \n" ); document.write( "
