jesse takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. a hamster weighs half a pound and costs $2 per week to feed, while a labrador retriever weighs 62.5 pounds and costs $10 per week to feed. using weight as the explanatory variable, what is the slope of a line between these two points? answer choices are rounded to the nearest hundredth. $7.75 / lb. $6.25 / lb. $4.00 / lb. $0.13 / lb.
