you drain a 200 liter aquarium at consant rate of 20 liters per mintue
what is independent quantity and dependent ?
draw a graph showing the independent quantity on the axis and dependent quantity on the y -axis .
To determine the independent and dependent quantities, we need to understand the relationship between the variables involved.
In this scenario, the independent quantity is the time (minutes), as it is the variable that we have control over. The dependent quantity is the amount of water drained from the aquarium (liters), as it depends on the amount of time that has passed.
To represent this relationship graphically, we can plot the independent quantity (time) on the x-axis and the dependent quantity (amount of water drained) on the y-axis.
The graph will be a straight line with a negative slope because as time increases, the amount of water drained from the aquarium increases. Here's how it looks:
```

The x-axis represents time in minutes, and the y-axis represents the amount of water drained in liters.
