Determine whether the lines x-5y=15 and -5x-y+2=0 are parallel, perpendicular, or neither.
\n" ); document.write( "I really need help with this one. Kim \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x - 5y = 15 has a slope of \"1%2F5\", while - 5x - y + 2 = 0 has a slope of \"-+5\". \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since these two slopes are negative reciprocals of each other: \"1%2F5\" and \"-+%285%2F1%29\", then the slopes are perpendicular to each other.
\n" ); document.write( "
\n" );
