You can put this solution on YOUR website!
The slope of y=3x+4 is 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The slope of y=ax+2 is 'a'.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Parallel lines have equal slopes.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the slope of y=ax+2 must also be 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, a = 3\r
