At the end of a snow storm, Eli saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. The depth of
snow on Eli's lawn, in inches, can be modeled by the equation S = 16 – t, where t
is the time, in hours, after the snow stopped falling. What is the y-intercept of the
equation and what is its interpretation in the context of the problem?
