The table represents a bicycle rental cost in dollars as a function of time in hours. A table showing Bicycle Rental with 2 columns and 6 rows. The first column, Time in hours, has the entries, 0, 2, 4, 6, 8. The second column, cost in dollars, has the entries, 0, 10, 20, 30, 40. 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.

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:

Given

Time  ------ 0 ----- 2 ------- 4 ----- 6 -----8.

Cost ------- 0 ----- 10 ----- 20 ----30 ----40

Required

Explain why or why not it is a direct variation?

First, we calculate the slope of the table.

Where:

So:

Next, we determine the equation using

The above shows a direct variation with 5 as its constant of proportionality of variation.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
