(b) Interpret the slope and y-intercept, if appropriate. First interpret the slope. Select the correct choice below and, if necessary, fill in the answer box to complete your choice OA. For an index score of zero, the commute time is predicted to be (Round to three decimal places as needed) OB. For every unit increase in commute time, the index score falls by (Round to three decimal places as needed) minutes OC.
