Answer 1

The y intercept is the starting depth of the snow. In this case, it would be 18 inches (aka 1 ft + 6 inches aka 1.5 feet)

The y intercept is the starting value and it occurs when t = 0

S = -2t+18

S = -2(0)+18

S = 0+18

S = 18

At time t = 0, the depth of the snow is S = 18 inches. As t increases, the value of S will decrease.
