For this case we have the following linear equation:
d = 15.7p + 2.0
Where,
p: number of people
d: total bill
We note that the slope of the equation is:
m = 15.7 $ / person
Therefore, the amount of the bill increases if the number of people grows.
Answer:
b) The model predicts that for each additional person at a table, the total bill increases by $ 15.70.
The product of the -72 could be set up at -72=-9(x).
Divide -9 from both sides and you get the unknown value (x) to be 8
L' and K' need to be moved to the right one unit but other than that you did it correctly. You'll just have to sort of guess where the top points would be.
Since there are 2 length sides and 2 width sides, the best equation to represent the perimeter would be 2x + 2(10) = P
