In Problem 17-36, solve each equation algebraically. Verify your solution using a graphing utility.
A cereal company finds that the number of people who will buy one of its products in the first month that it is introduced is linearly related to the amount of money it spends on advertising. If it spends \(40,000 on advertising, then 100,000 boxes of cereal will be sold, and if it spends \)60,000, then 200,000 boxes will be sold.
(a) Write a linear equation that relates the amount A spent on advertising to the number x of boxes the company aims to sell.
(b) How much advertising is needed to sell 300,000 boxes of cereal?
(c) Interpret the slope.
Does every line have exactly one x intercept and one y-intercept? Are there any lines that have no intercepts?
Graph the line containing the point P and having slope m.
