For a few months, Dexter recorded the amounts, in fluid ounces, of laundry detergent remaining y after he and his family washed x loads of laundry. The equation of the line of best fit for his data is shown below. y = -1.6x + 50 Which statement correctly describes the slope of Dexter’s equation of the line of best fit in the context of the situation? A. The bottle Dexter’s family buys holds about 50 fluid ounces of detergent. B. For each load of laundry, Dexter’s family used about 1.6 fluid ounces of detergent. C. With 50 fluid ounces of detergent, Dexter’s family can wash about 1.6 loads of laundry. D. With 1.6 bottles of laundry detergent, Dexter’s family can wash about 50 loads of laundry.

Mark and Jessica are each making a linear model to predict the population of squirrels in the town park. The are both using the same data points to find an equation of the line of best fit: the squirrel population, p, in 2002 and the squirrel population, q, in 2011. Mark is using the year as the x-value, and he represents his data as (2002, p) and (2011, q). Jessica is using the years since 2000 as her x-value, and she represents her data as (2, p) and (11, q). Which statement best describes how their prediction equations compare? Their equations have the same slopes and y-intercepts. Their equations have different slopes and y-intercepts. Their equations have different y-intercepts but the same slopes. Their equations have the same y-intercepts but different slopes.
