Answer: 8.8 pounds.
Step-by-step explanation:
Hi, to answer this question, first we have to divide the total weight loss in a week (28 kg) by 7 (days in a week).
28 /7 = 4 kg per day
The group lost 4 kg each day.
Finally we have to convert the result into pounds.
Since 1 kg = 2.2 pounds
4 kg x 2.2 = 8.8 pounds.

Answer:
y = -11x + 9
Step-by-step explanation:
m = -11
x = -1
y = 20
Plug those values into the equation to find b: y = mx + b
20 = (-11)(-1) + b
---> b = 9
Plus m = -11 and b = 9 into y = mx + b
---> y = -11x + 9
