The water level of a lake has been increasing each year. The initial water level of the lake was 800 meters, and the water level increases by 1 m each year. Use this information to answer the questions below.

Since the water level increases by 1 m each year, the increase in water level is the same as the number of years. Write an equation relating final water level (w) to the time in years (t).
