Question

At the end of a snow storm, Jace 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 Jace's lawn, in inches, can be modeled by the equation S, equals, 15, minus, 1, point, 5, t, commaS=15−1.5t, where tt is the time, in hours, after the snow stopped falling. What is the yy-intercept of the equation and what is its interpretation in the context of the problem?

Answer 1

The y-intercept is 15 (the point (0, 15)). It means that at t = 0 hours (right after the snow stopped) the snow depth was 15 inches.
