\n" ); document.write( "Need to sketch graphs
\n" ); document.write( "2x+7 Blue a = 2
\n" ); document.write( "2x-3 Green (Green and Blue //)
\n" ); document.write( "-.5x + 7 b = -1/2 (Perpendicular to the Above)
\n" ); document.write( "2x-3 = -.5x + 7, x = 4 and y = 5, (4,5) & (0,7) points of intersection
\n" ); document.write( "(0,7)
\n" ); document.write( "(4,5) sqrt(16 +4) = sqrt(20), perpendicular distance between the pair of parallel lines.
