parallel lines have the same slope
\n" ); document.write( "a: NOT parallel, for they have different slopes. They do intersect.
\n" ); document.write( "You can determine that point by setting them equal to each other.
\n" ); document.write( "-20x+13= 3.7x-13
\n" ); document.write( "-23.7x= -26
\n" ); document.write( "x=(26/23.7)
\n" ); document.write( "======
\n" ); document.write( "b. The third, and fourth functions are all parallel, for they both contain y=3.6x.
\n" ); document.write( "====
\n" ); document.write( "For every one of the five functions given.
\n" ); document.write( "y=-20x+13 is parallel to y=-8-20x
\n" ); document.write( "y=3.6x+8 and y=3.6 x are parallel to each other.
\n" ); document.write( "
\n" ); document.write( "
\n" );
