Please help !! I don’t understand :( I’ll mark ! Thanks

Step-by-step explanation:

By examining the different parts of this equation and what they mean in the context of this problem, we can use the equation to find out different pieces of information about the scenario.

An equation in the form is set up in the way that m = slope, and b = y-intercept.

When starting on a graph, you start at x = 0. Plugging 0 into the equation as x leaves y as 1200. This shows that the base price to make a book is

$1200.

Also, the equation shows that the slope of the line is 15. If we were to put this on to a graph, then every time x (books) increases by 1, y (cost) would increase by 15. Therefore, books cost $15 per book to publish. This makes it the total cost for every book published.

Hope this helped!
