Hello!

The answers are:

  • $1200
  • $25(+)

Why?

For the first question, if there is no printed book, the variable x will be 0, so:


y=1200+15x\\y=1200+15(0)

The cost to get started, meaning that there is not any printed book, is $1200

For the second question, to determine the change in the total cost for each printed book, let's assume that there is just one book printed, so:


y=1200+15x\\y=1200+15(1)=1215

So, the change for each printed book is $15(+) because:


Change=(1)BookPrintedCost-NoBookPrintedCost=1215-1200=15

Have a nice day!

Answer:

a) 1200

b) +15

Explanation:

The given equation is


y=15x+1200

The cost to get started is the initial cost(y-intercept) which is
1200.

The change in total cost for each book printed is the slope of the line which is
+15
