In this problem, \( y = 80 \) represents the temperature of the water after 6 minutes have passed since Micah started heating it. Therefore, the correct interpretation is:
The water temperature will be 80 degrees after 6 minutes.
This equation shows the linear relationship between the number of minutes since Micah started heating a pot of water and the temperature of the water. x represents the number of minutes, and y represents the temperature in degrees Celsius.
You just substituted 6 for x and found that y=80. What does y=80 represent in this problem?
y

80
The water temperature increases
80 degrees every 6 minutes.
The water temperature
increased 80 degrees.
The water temperature will be
80 degrees after 6 minutes.
