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 a constant rate. The equation shows the ice sheet's thickness, S, measured in meters, t weeks after it begins to melt. Interpret the slope

S = -0.25t + 4

After each week, the ice thickness has decreased by 0.25 m

After each week, the ice thickness has increased by 0.25 m

After each week, the ice thickness has decreased by 4 m

After each week, the ice thickness has decreased by 4 m
