If the relationship is P = 3c, we ask
\n" ); document.write( "\"Does it take the form y = kx?\"
\n" ); document.write( "The answer is yes, and so it is a direct relationship,
\n" ); document.write( "and P is directly proportional to c.
\n" ); document.write( "When one doubles, the other doubles, and so on...
