The water level in noah's water tank is 72 inches high. noah begins to drain a water tank by opening a valve. the water drains at a speed up 5 inches per minute. write an equation for slope.

The required equation of slope is given by

Step-by-step explanation:

Since we have given that

Length of the water level in Noah's water tank = 72 inches

Speed at which water drains = 5 inches per minute

Let the  height of the tank be y.

Let the number of minutes be x.

So, the equation of slope is given by

which represents the height of water level of 72 inches is reduced by 5x inches as

Hence, the required equation of slope is given by
