The tortoise and the hare are going to have a rematch. But the hare is smarter this time, and doesn't want to fall asleep while the tortoise gets ahead. But to keep things interesting, the hare gives the tortoise a certain length of head start: \frac{1}{5} of a staid. So, at the start of the race, the tortoise starts \frac{4}{5} of a staid from the finish line. And the hare starts 1 staid from the finish line.
A graph shows the tortoise's distance from the finish line y, in staids, after x minutes. What is the ^y-intercept of the graph and what does it represent?

(0,0); the tortoise's initial starting point.

\frac{1}{5}; the length of the tortoise's head start.

(0,\frac{4}{5}); the tortoise's initial distance from the finish line.

6; the number of minutes it takes for the tortoise to finish the race.
