2y - 8x = 16
\n" ); document.write( "y = 1/4x - 5
\n" ); document.write( "---
\n" ); document.write( "2y = 8x + 16
\n" ); document.write( "y = 1/4x - 5
\n" ); document.write( "---
\n" ); document.write( "y = 4x + 4
\n" ); document.write( "y = 1/4x - 5
\n" ); document.write( "---
\n" ); document.write( "the slopes of the two lines (4 and 1/4), are neither equal nor negative reciprocals, therefore the lines are neither parallel nor perpendicular
