Option (D) the box weighs 9 ounces and each book weighs 14 ounces is the correct answer.

What is a linear equation?

A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

For the given situation,

The equation is y = 14x + 9.

Let y represents the total weight in ounces of the books and the box.

Let x be the number of books.

Then from the equation, the box weighs 9 ounces and each book weighs 14 ounces.

Based on number of books, the total weight 'y' varies accordingly.

Hence we can conclude that option (D) the box weighs 9 ounces and each book weighs 14 ounces is the correct answer.
