Question 1164828: 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.
 Assume that the relationship between sales​ price, x, and number of Fun Noodles​ sold, ​ y, is linear. Write an equation in​ slope-intercept form describing this relationship. Use ordered pairs of the form​ (sales price, number​ sold).
predict the daily sales of fun noodles if the price is $4.50

Points (x,y) for the description are (4, 8000) and (6, 6000). You could start your equation in point-slope form and then solve for y from it.

y-6000=%28%286000-8000%29%2F%286-4%29%29%28x-6%29-------simplify this. Solve for y in terms of x. Keep in form y=mx+b.
