Question 912781: The y-variable is the cost in dollars to produce or publish x number of books for a publisher. The cost, y, to make x books is $3 per book plus a fixed cost of $1500. The cost, y, and the number of books made, x, are linearly related. In this scenario, the y-variable is measuring cost (to publish) with units of dollars and the x-variable is measuring the number of books (published) with units of books.

Linear Equation model for the cost, y

y=mx+b and you should decide that the slope is a ratio, being the book cost for each book, so cost/book multiplied by quantity of books is the cost for the books without any additional costs; but you have a fixed, additional cost.
