<span>39 & 16.5 = -22.5 30 & 12.4 = -17.6 28 & 10.4 = -17.6 19 & 10.3 = -8.7 23 & 11.2 = -11.8 if the values are y values you will subtract them from each other to get the numerical value and because they all go from a larger number to a smaller number the rate is a negative. if they were from a smaller value to a larger value teh rates of change would be positive. </span>
