Interpret the estimated slope of the line.
◦ For a 1-point increase in an administrator's rating, we estimate the administrator's raise to decrease $2,000.
◦ For an administrator with a rating of 1.0, we estimate his/her raise to be $2,000.
◦ For a $1 increase in an administrator's raise, we estimate the administrator's rating to decrease 2,000 points.
◦ For a 1-point increase in an administrator's rating, we estimate the administrator's raise to increase $2,000.
