An 8th grade class develops a linear model that predicts the number of cheerios (a small round cereal) that fit on the
circumference of a plate by using the diameter in inches. Their model is chee^rios = 0.56 + 5.11(diameter).
-The slope of this model is best interpreted in context as…
A) For every 1 inch of diameter, the circumference holds about 0.56 more cheerios.
B) For every 1 inch of diameter, the circumference holds about 5.11 more cheerios.
C) For every 5.11 inches of diameter, the circumference is about 1 cheerio bigger.
D) It takes 5.11 cheerios to fill a plate's circumference.
E) A mistake, because π is about 3.14 and that should be the slope.

The slope of the model represents the change in the number of cheerios for every 1-unit change in the diameter. In this case, the slope is 5.11, which means that for every 1-inch increase in the diameter, the circumference holds about 5.11 more cheerios.
