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.

Part A
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).

The water level starts at 800. Then, with each year, we add a meter. It means that after t years we add exactly t meters.

So, at any given time t, the water level will be

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
