Which choice could be the equation of a line perpendicular to the line represented by this equation?
\n" ); document.write( "y = 2/5x + 2
\n" ); document.write( "-----------------
\n" ); document.write( "The slope of lines perpendicular is the negative inverse of the slope of the given line.
\n" ); document.write( "-----
\n" ); document.write( "-1/(2/5) = -5/2
\n" ); document.write( "
\n" ); document.write( "
\n" );
