Raphael is performing an experiment where he is measuring the evaporation
rate of water. He records the depth of the water in a bucket, measured in
centimeters, for ten days. A linear equation that models the results of his
experiment is y = -0.6x+8. What does the slope of this model suggest about
the evaporation rate?

A. The height of the water increases about 0.6 cm per day.

B. The height of the water decreases about 0.6 cm per day.

C. The height of the water increases about 0.6 cm over ten days.

D. The height of the water decreases about 0.6 cm over ten days,
