Find slope of the given points and find slope of the line perpendicular;
\n" ); document.write( "Find the midpoint of the given points;
\n" ); document.write( "Use either equation form you are comfortable with and form the equation for the perpendicular line
\n" ); document.write( "which contains the midpoint.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m%5Bg%5D=%28-3-%28-5%29%29%2F%28-2-2%29=2%2F%28-4%29=-1%2F2\", \"given\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m%5Bg%5D%2Am=-1\", to ensure m is for the needed perpendicular line.\r
\n" ); document.write( "

\n" ); document.write( "\"x=%28-2%2B2%29%2F2=highlight_green%280%29\";
\n" ); document.write( "\"y=%28-3-5%29%2F2=highlight_green%28-4%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You want the equation for the line with slope 2 and passing through point (0,-4).
\n" ); document.write( "The rest of this is not done, so that you will do it, finish.
