Here is a piecewise linear model for the water height in feet of a reservoir that supplies water to a nearby town over a 12-month period.

A scatterplot, horizontal, months, 0 to 12, vertical, height of water in feet, 6660 to 6740. points trend downward from months 0 to 3, then upward to month 6, then horizontal to month 7, then downward to month 12.

Select all the true statements.

A large university campus has two bike sharing programs students can pay for each month.

• Program A advertises that they charge 34 dollars to join and 1 dollar per mile traveled.
• Program B advertises that their fee to join is less than 50 dollars and that they charge less per mile than Program A.

1. Which program is represented by line $\ell$?
2. If $c$ is the cost in dollars and $m$ is the distance traveled in miles for a month, write a possible equation to represent Program B.
