Algebra.Com's Answer #640780 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! The graph of \n" ); document.write( "(x-3)^2 + (y-5)^2 = 16 \n" ); document.write( "is a circle centered at (3,5) with radius of 4. \n" ); document.write( "When you reflect over the line y = 2, it is still a circle of radius 4 but its new center is at (3,-1), and its new equation is \n" ); document.write( "(x-3)^2 + (y+1)^2 = 16 \n" ); document.write( "Now multiply everything out and get \n" ); document.write( "x^2 - 6x + 9 + y^2 + 2y + 1 = 16 \n" ); document.write( "x^2 - 6x + y^2 + 2y - 6 = 0 \n" ); document.write( "B+D+F = -10 \n" ); document.write( " |
