Sorry, another math problem please

Hooke's Law asserts that the force required to either stretch or compress a spring from its natural length varies as the displacement. A certain spring is stretched 12 inches beyond its natural length by a 3 lb. weight. Express the force in terms of the displacement for this spring.

force in term of dispacement?
3lb/12in or 1lb/4inches 
Oh really? Is that all was meant? Perhaps I was thinking along too complex lines.
Thanks, I appreciate it. 
Probably 4oz/inch iz best.
