At the end of a snow storm, Nolan 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 Nolan's lawn, in inches, can be modeled by the
equation S = -1.75t + 14, 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?
