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?

0 pizzas

21 pizzas

43 pizzas

60 pizzas

70 pizzas

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

c

step-by-step explanation:

she will most likely have 33  

step-by-step explanation:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
