You can put this solution on YOUR website!
The line you want will be perpendicular to the line
\n" ); document.write( "through the points (-6,4) and (0,8), so you know that
\n" ); document.write( "if y=mx + b is the equation of the line through
\n" ); document.write( "(-6,4) and (0,8), then the slope of the perpendicular is
\n" ); document.write( "-1/m. If it's midway between the points, you need to sind that
\n" ); document.write( "midpoint.
\n" ); document.write( "First find the slope you want.

\n" ); document.write( "check this. Does this line go through (-6,4) and (0,8)?
