Final answer:
To graph the amount of liquid remaining in the vat at any hour, we can use the equation y = 16 - 2x.
Step-by-step explanation:
To graph the amount of liquid remaining in the vat at any hour, we can use a linear equation.
The initial amount of liquid in the vat is 16 gallons. The drain pipe removes 2 gallons per hour. Therefore, the remaining amount of liquid in the vat after x hours can be represented by the equation: y = 16 - 2x.
To graph this equation, we can plot the values of x on the x-axis and the corresponding values of y on the y-axis. Each point on the graph will represent the amount of liquid remaining in the vat at a specific hour.
