Question

The graph shows the relationship between fees charged for downloading songs from a website and the number of songs downloaded. Which equation represents the relationship?

Answer 1

Answer:

B. y = 0.50x

Step-by-step explanation:

f (x) = y = Fees

x = number of songs downloaded

The graph shows that f (x) = y = 0.50x

This can be corroborated when we see that at each given point an ordered pair is generated in which the value of "x" is double the value "y", or seen from another perspective the value of "y" is half the value of "x", that is y = 0.50x.

For x = 4, y = 0.50 (4) = 2. Ordered pair (4,2).

For x = 10, y = 0.50 (10) = 5. Ordered pair (10,5).

For x = 16, y = 0.50 (16) = 8. Ordered pair (16,8).

In conclusion, the fee corresponds to half the amount of songs downloaded, that's y = 0.50x.

Hope this helps!

Answer 2

B y=0.50x because if you plug it in you see that it works for each of the points on the graph. For example, 2=0.50(4) and 5=0.50(10), etc.
