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 500

 liters in the pond to start.

Let 

W

represent the amount of water in the pond (in liters), and letT

represent the number of minutes that water has been added. Write anequationrelatingW

toT

,and then graph your equation using the axes below.

Answer 1

Equation can be formed as:

Water = time pumping at 25 litres per minute + initial amount of 500L

Hence,

$W = 25t+500$

OR

$y = 25x + 500$

For plotting the graph we have to find at least two points.

$x = 0, y = 500$

$x = -20,y = 0$

Graph will look like this:
