The pool fun company has learned that, by pricing a newly released fun noodle at $4, sales will reach 8000 fun noodles per day during the summer. raising the price to $6 will cause the sales to fall to 6000 fun noodles per day. write an equation in slope intercept form describing this relationship. use ordered pairs of the form (sales price, number sold)
