Part A — Select:
- How the number of dance tickets sold relates to the amount of money raised.
- The total number of miles biked if you travel the same distance each day.
Reason: both are direct-proportion situations (amount = rate × quantity), which match the straight line through the origin.
Part B — Equation:
y = 15x
(That equation is a direct variation with slope 15, matching the graph.)
