Question

Michhnne's Phone Service charges $18.o9 for an activation fee plus $2 for every gigabyte (g) used. Which of the following graphs models the situation

Answer 1

For this case we have:

A function of the form
`y = f (x)`, where f (x) is given in a linear fashion as:

`f (x) = mx + b`

Where m: Is the slope, in this case, $ 2 is charged for each gigabyte used.

b: Represents the activation rate

Rewriting we have:

`f (x) = 2x + 18.09`

Where x represents the amount of gigabyte used

Answer:

See attached image

`f (x) = 2x + 18.09`
