The scatter plot below shows the number of pizzas sold during weeks when different numbers of coupons were issued. the equation represents the linear model for this data.

y = 3.4x + 43

according to the model, what is the average number of pizzas sold in one night if no coupons are issued?

a. 0

b. 21

c. 43

d. 60

e. 70

The average number of pizzas sold in one night if no coupons are issued is 43.

Step-by-step explanation:

In the scatter plot the average number of pizzas sold is represented on x and number of coupons issued is represented on y.

The trend line of this linear model is

So, when no coupons are issued then the value of x becomes 0, then putting the value of x in the equation,

Therefore, the average number of pizzas sold in one night if no coupons are issued is 43.

step-by-step explanation:

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
