y = 6x – 15
\n" ); document.write( "is in the \"slope-intercept\" form
\n" ); document.write( "y = mx + b
\n" ); document.write( "where
\n" ); document.write( "m is slope
\n" ); document.write( "b is the y-intercept
\n" ); document.write( ".
\n" ); document.write( "To be parallel, slopes are identical.
\n" ); document.write( "So, our new line has
\n" ); document.write( "m = 6
\n" ); document.write( "and crosses
\n" ); document.write( "(0,0)
\n" ); document.write( ".
\n" ); document.write( "Plug the above into the \"point-slope\" form
\n" ); document.write( "y - y1 = m(x-x1)
\n" ); document.write( "y - 0 = 6(x-0)
\n" ); document.write( "y = 6x (this is what they're looking for)
\n" ); document.write( "
\n" );
