A lake near the Arctic Circle is covered by a thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a rate of 0.2 meters per week. After 7 weeks, the sheet is only 2.4 meters thick.

Let y represent the ice sheet’s thickness (in meters) after x weeks.

Complete the equation for the relationship between the thickness and number of weeks.
