Algebra.Com's Answer #368274 by Theo(13342)![]() ![]() You can put this solution on YOUR website! standard form of equation of a circle is: \n" ); document.write( "(x-h)^2 + (x-k)^2 = r^2 \n" ); document.write( "(h,k) is the center of the circle. \n" ); document.write( "r is the radius. \n" ); document.write( "in your equation, this becomes: \n" ); document.write( "(x+2)^2 + (y+4)^2 = 36 \n" ); document.write( "to graph your equation, solve for y to get: \n" ); document.write( "y = +/- sqrt(36 - (x+2)^2) - 4 \n" ); document.write( "that graph is shown below: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
