Answer:

Step-by-step explanation:
Given
Number of service bays 
Time taken by each bay to finish one oil change 
Working capacity
hours per day
Thus, in
hours the total number of times one bay has changed the oil is equal to

If one service bay's capacity is equal to
, capacity of two service bays is equal to

Thus, the design capacity is 
If you mean standard 8.5x11 paper then 3 papers wide would make it 25.5in or 2.13 feet.
y=6x-3
put a point on (0,-3) this is your y intercept
go up 6 and over 1 this should land you at (1,0) do this again and your at (2,6)
go back to the y intercept now go down 6 and over 1, this should land you (-1,-6)
continue to do this until you graph is filled
