Answer:
You will want to add up the total for all four guests (The one after you added the tip) and then since you want to split it evenly, you can multiply it by 1/4.
First point given: (5,4)
Y = -1/4x + b
4 = -1/4(5) + b
4 = -5/4 + b
b = 2.75
Equation: y = -1/4x + 2.75
Find three points
(5,4), (9,5), (1,3)
Plot these and draw a line
From the table, we can observe that the formula for the total cost of item is

From the data in the table, cost of item 6.00 has the input incorrect because the sum of the cost of its item and tax on the item is,

but the total cost was incorrectly inputed as 7.56.
