Owners of a recreation area are filling a small pond with water. They are adding water at a rate of 25 liters per minute. There are 700 liters in the pond to start. Let W represent the amount of water in the pond (in liters), and let T represent the number of minutes that water has been added. Write an equation relating w to T, and then graph your equation.

Question

Owners of a recreation area are filling a small pond with water. They are adding water at a rate of  25 liters per minute. There are 700 liters in the pond to start. Let W represent the amount of water in the pond (in liters), and let T represent the number of minutes that water has been added. Write an equation relating w  to T, and then graph your equation.

How would I graph this? The equation should be in fraction form, if possible.

Damon · Answer

constant change with time so straight line of constant slope at T = 0, w = 700 so (0,700) is on the line slope = 25liters/min w = m T + b w = 25 T + 700
