An internet service provider allows a certain number of free hours each month and then charges for each additional hour used. wells, ted, and vino each have separate accounts. this month the total hours used by wells and ted was 105, and each used all of their free hours. their total cost was $\$10$. vino used 105 hours by himself and had to pay $\$26$. what is the number of cents charged for each extra hour

Step-by-step explanation:

Wells and Ted used 52.5 hr each (free hours)  and paid 10$

Vino used 105 hr:

He paid 26$ (the 10$ of the free hours and 16$ for the extra):

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
