At the end of a snow storm, Caleb 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 Caleb's lawn, in inches, can be modeled by the equation S=-2t+18,S=−2t+18, 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?

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

6 and 24

step-by-step explanation:

6 x 4 = 24
