The table represents a bicycle rental cost in dollars as a function of time in hours. Which explains whether or not the function represents a direct variation? This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour. This function represents a direct variation because it has a positive, constant rate of change of $10 per hour. This function does not represent a direct variation because it does not represent the cost for 1 hour. This function does not represent a direct variation because the function rule for the cost is to add $10, not multiply by a constant.

Answer:
This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
Step-by-step explanation:
Table
Time in Hrs Cost ($)
0 0
2 10
4 20
6 30
8 40
Cost = a (hrs) + b
C = aH + b
0 = 0 + b
b = 0
C = aH
10 = a2
=> a = 5
=> C = 5H
Cost Per hour = 5 $
This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
