please help me.find the equation of acircle that passes through points (3,5) (6,7) (8,9)?
\n" ); document.write( "--------------
\n" ); document.write( "Find the equation of the 2 lines from (3,5) to (6,7) and from (6,7) to (8,9)
\n" ); document.write( "Find the midpoints of the 2 line segments, then find the eqns of 2 lines thru the midpoints perpendicular to the lines.
\n" ); document.write( "----------
\n" ); document.write( "The solution of the 2 equations is the intersection of the 2 lines at the center of the circle.
\n" ); document.write( "The radius is the distance from the center to any of the 3 points.
\n" ); document.write( "--------------
\n" ); document.write( "x^2 + y^2 + 9x - 39y = -134 is the equation
\n" ); document.write( "center at (-4.5,19.5)
\n" ); document.write( "
\n" );
