Each dot in the scatterplot above represents an apartment listing in a city, where x is the distance from downtown (in kilometers) and y is the monthly rent (in hundreds of dollars). A line of best fit for the data is shown, and one data point is labeled P.
The residual for a point is defined as
(actual rent)−(rent predicted by the line of best fit).
Suppose the monthly rent for the apartment represented by point P decreases by $200, and the line of best fit is shifted upward by 0.4 (hundreds of dollars) at every x-value.
Which choice gives the new residual for point P, in dollars?
