PLEASE HURRY I WILL GIVE BRAINLEIST x + 3 = -x - 5

1 - 2x = -x - 3

x - 2 = -3x + 2

3y + 1 = 4y - 6

2 + 6x = 1 - x

5y + 4 = 4y + 5

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
