Do you mean the minimum distance to the line?
\n" ); document.write( "If so, the minimum distance is a perpendicular line going through the point.
\n" ); document.write( "A perpendicular line would have the form,
\n" ); document.write( "\"y=-%281%2F2%29x%2Bb\"
\n" ); document.write( "Use the point to solve for \"b\".
\n" ); document.write( "\"-3=-%281%2F2%29%286%29%2Bb\"
\n" ); document.write( "\"-3=-3%2Bb\"
\n" ); document.write( "\"b=0\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Find the intersection of the two lines.
\n" ); document.write( "\"y=-%281%2F2%29x\"
\n" ); document.write( "\"y=2x-5\"
\n" ); document.write( "Set them equal to each other.
\n" ); document.write( "\"-%281%2F2%29x=2x-5\"
\n" ); document.write( "\"-x=4x-10\"
\n" ); document.write( "\"-5x=-10\"
\n" ); document.write( "\"x=2\"
\n" ); document.write( "Then from either equation, solve for \"y\".
\n" ); document.write( "\"y=-%281%2F2%29%282%29=-1\"
\n" ); document.write( "Now find the distance from (6,-3) to (2,-1) using the distance formula,
