The correlating linear model is shown below, where \( x \) represents the number of sugary snacks a student ate, and \( y \) represents the student's test score. Interpret the rate of change (slope). \[ y=-5 x \] (A) Eating zero sugary snacks is associated with a loss of five points on the test. (B) Each additional sugary snack eaten is associated with a loss of five points on the test. (C) An additional five sugary snacks is associated with a loss of five points on the test. (D) Not enough information is provided to interpret the slope.
