The coordinates of the fifth point that Julian plots are (15, 2500).
The significance of the fifth point that Julian plots are, that on the 5th day of the week Julian gives a total of 15 Liters of water and 2500 grams of food to his dog, Banjo.
Given: Julian gives 3 Liters of water and 500 grams of food to his dog every day.
As no other information is given, so we can say that every day Julian gives exactly 3 Liters of water and 500 grams of the food. That means if we see the total amount of water and food consumed by his dog, the quantity of water and food will increase linearly.
Also Julian plot the amount of water and food given to his dog, a graph where the amount of water is on the x-axis and the amount of food consumed is on the y-axis. The first point on the graph is already marked by Julian is (3, 500).
Now Julian plots the points for the consumption for the next 6 days.
So we draw the graph of "Liters of water" vs "grams of food".
So, the coordinates of the first given point are (3, 500)
The coordinates of the second given point : (6, 1000)
The coordinates of the third given point : (9, 1500)
The coordinates of the fourth given point : (12, 2000)
The coordinates of the fifth given point : (15, 2500)
The coordinates of the sixth given point : (18, 3000)
The coordinates of the seventh given point : (21, 3500)
Therefore from the graph, we can conclude that the coordinates of the fifth point are (15, 2500)
Hence, the significance of the fifth point that Julian plots are, that on the 5th day of the week Julian gives a total of 15 Liters of water and 2500 grams of food to his dog, Banjo.
