\n" ); document.write( "Show that point (0,-1),(6,7),(-2,3),(8,3) are vertics of rectangle
\n" ); document.write( "

If this is a rectangle, adjacent sides are perpendicular to each other. For adjacent sides to be perpendicular to each other, their slopes MUST be NEGATIVE reciprocals of each other. 
\n" );
document.write( "In other words, if the rectangle is named ABCD, with A being (0,- 1), B being (8, 3), C being (6, 7), and D, (- 2, 3), AB and CD MUST be perpendicular to BC and AD. 
\n" );
document.write( "Additionally, you'd need to find the length of the sides, and if AB = CD, and AD = BC, then this is DEFINITELY a rectangle. \n" );
