Can someone help me figure this chart out please

From top to bottom

9

27/2

108/6

135/3

Step-by-step explanation:

Find how much is in 1 hour (unit rate)

Do 9/2 x 3=27/2

27/2 x 2/3=54/6=9

4/3 x 27/2= 108/6

Notice how all are solved with the unit rate

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
