ankoles [38]

Answer:  A. There were 500 liters in the tank when the leak started, and it is  decreasing by 9 liters per minute.

Step-by-step explanation:

This equation is in the form; y =mx + c.

<em>c</em> in this equation is the value of y when x is at 0.

<em>c</em> in the above formula is 500 which means that the number of litres (y) at zero minutes(x) is 500 litres.

<em>m</em> is the rate of change as a result of a change in x.

<em>m</em> in this equation is -9 which means that the water is reducing by 9 litres every minute (x).
