\n" ); document.write( "recall, the slope values are negative reciprocals if lines perpendicular; \"m%5Bp%5D=-%281%2Fm%29\" \r
\n" ); document.write( "\n" ); document.write( "given\r
\n" ); document.write( "\n" ); document.write( "\"y%2B4x=-7\"...write in slope-intercept form \"y=mx%2Bb\"\r
\n" ); document.write( "\n" ); document.write( "\"y=-4x-7\"...so, slope \"m=-4\"\r
\n" ); document.write( "\n" ); document.write( "then the slope of a line perpendicular to \"y=-4x-7\" will be\r
\n" ); document.write( "\n" ); document.write( "\"m%5Bp%5D=-%281%2F-4%29\"\r
\n" ); document.write( "\n" ); document.write( "\"m%5Bp%5D=1%2F4%29\"
