Re: 7x + 11y = N

Hi Amctest 123

Welcome to the forum.

There is an entire "family" of straight lines where 7x+ 11y = something.

They are all parallel and as N gets bigger the lines move away from the origin. Joining (11,0) to (0,7) will produce one.  What is N for this case?

That should give you a starting point.
