1)Write an equation of the circle with center (1,-1) if (-1/2,-1) lies on the circle
\n" ); document.write( "-------
\n" ); document.write( "EQUATION:
\n" ); document.write( "(x-1)^2 + (y+1)^2 = r^2
\n" ); document.write( "If it passes thru ((-1/2),-1), solve for r as follows
\n" ); document.write( "(-1/2 - 1)^2 + (-1+1)^2 = r^2
\n" ); document.write( "(-3/2)^2 + 0^2 = r^2
\n" ); document.write( "r = (3/2)
\n" ); document.write( "EQUATION:
\n" ); document.write( "(x-1)^2 + (y+1)^2 = (9/4)
\n" ); document.write( "-----------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2) The slope of any line perpendicular to the line y=-1/3x-4
\n" ); document.write( "The given line has a slope of -1/3
\n" ); document.write( "Any line perpendicular to it must have a slope of 3/1
\n" ); document.write( "-----------------------------
