Algebra.Com's Answer #435344 by Alan3354(69443) You can put this solution on YOUR website! the circle passes through the points A(-5,2) and B(-1,4) and tangent to the line x-5y=10. \n" ); document.write( "1. radius of the circle \n" ); document.write( "2. equation of a circle in a center-radius form \n" ); document.write( "3. equation of circle in general form \n" ); document.write( "================================== \n" ); document.write( "Find the eqn of the perpendicular bisector of the line thru A & B. The center is on that line. \n" ); document.write( "---- \n" ); document.write( "The intersection of the perp bisector and x-5y=10 is a point on the circle, point C. \n" ); document.write( "Find the perp bisector of AC. \n" ); document.write( "The intersection of the 2 perp bisectors is the center. \n" ); document.write( "--- \n" ); document.write( "The radius is the distance from the center to A, B or C.\r \n" ); document.write( "\n" ); document.write( "Find the \n" ); document.write( " |
