Find the center of the circle by solving for x & y \r
\n" ); document.write( "\n" ); document.write( "1 x + 3 y = -7 .............1
\n" ); document.write( "Total value
\n" ); document.write( "3 x -2 y = 12 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 2
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "2 x 6 y = -14
\n" ); document.write( "9 x -6 y = 36
\n" ); document.write( "Add the two equations
\n" ); document.write( "11 x = 22
\n" ); document.write( "/ 11
\n" ); document.write( "x = 2
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 3 y = -7
\n" ); document.write( "2 + 3 y = -7
\n" ); document.write( " 3 y = -7 -2
\n" ); document.write( " 3 y = -9
\n" ); document.write( " y = -3
\n" ); document.write( "center (2,-3) \r
\n" ); document.write( "\n" ); document.write( "point(-1,1)\r
\n" ); document.write( "\n" ); document.write( "Frame the equation \n" ); document.write( "
