A company set aside a certain amount of money in the year 2000. The company spent exactly the same amount from that fund each year on perks for its employees. In $2002$, there was still ${\$777{,}000}$ left in the fund. In $2007$, there was ${\$647{,}000}$ left. Let $x$ be the number of years since 2000, and let $y$ be the amount of money left in the fund that year. Use a linear equation to model the amount of money left in the fund after so many years.

1. The linear model’s slope-intercept equation is .
2. In the year $2011$, there was left in the fund.
3. In the year , the fund will be empty.
