The equation represents the linear model for this data. y = 3.4x + 43 According to the model, how many more pizzas are sold for each additional coupon issued? 1 pizzas 3.4 pizzas 4.3 pizzas 43 pizzas 46 pizza A graph measuring average number of pizzas sold nightly in relation to number of coupons issued. A line indicates that pizzas sold increases as number of coupons issued increases

Answer 1

Answer:

3.4 pizzas

Step-by-step explanation:

Given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

The trend line is given as

y =3.4x+43

This says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

Hence For each additional coupon issued 3.4 pizzas more will be sold
