Answer 1

The slope of the linear model equation \( y = 3.4x + 43 \) indicates how many more pizzas are sold for each additional coupon issued. In this equation, \( x \) represents the number of coupons issued, and \( y \) represents the number of pizzas sold.

The slope is 3.4, which means that for each additional coupon issued, 3.4 more pizzas are sold.

So the correct response is:

**3.4 pizzas**.
